Description

Technical Field

[0001] This invention relates to the field of filling technology, and more specifically, to a filling device. Background Technology

[0002] As people place increasing demands on quality of life and health, the market size for filling equipment is constantly expanding, and market requirements are also continuously rising. Currently, due to differences in technological innovation capabilities, marketing capabilities, and product quality, the competitive landscape among domestic filling equipment manufacturers varies.

[0003] Filling equipment typically includes a pipetting device and a conveying device. The conveying device has a pipetting station, where the pipetting device is located. The pipetting device first draws up liquid, and then injects the liquid into a bottle. After pipetting is complete, the filled bottle is conveyed to another location by the conveying device for further processing.

[0004] However, traditional filling equipment performs pipetting on a conveyor system. Since both the aspiration and dispensing of liquid by the pipetting device are time-consuming, the overall pipetting time is long. The conveyor system then needs to wait for a considerable period before transferring the pipetted bottles to the next station. As a result, the filling equipment has low efficiency and cannot achieve high-throughput filling. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, embodiments of the present invention provide a filling device. The filling device includes: a placement unit for holding bottles; a pipetting device including a first pipetting assembly, a second pipetting assembly, a pipette tip supply assembly, a pipette tip storage box, and a mother liquor supply assembly; in a first operating state, one of the first and second pipetting assemblies is used to draw liquid from the mother liquor supply assembly, and the other is used to inject the liquid into the bottle on the placement unit; in a second operating state, one of the first and second pipetting assemblies is used to attach a pipette tip to the pipette tip supply assembly, and the other is used to discard the pipette tip into the pipette tip storage box; a conveying device for receiving the filled bottle on the placement unit and sequentially conveying it along a conveying direction to a detection position and a receiving position; and a first detection device for detecting whether the bottle located at the detection position has defects.

[0006] For example, the pipetting device further includes a pipetting body and a rotary drive disposed on the pipetting body. The first pipetting assembly and the second pipetting assembly are disposed opposite to each other and are respectively connected to the drive end of the rotary drive. The rotary drive is used to drive the first pipetting assembly and the second pipetting assembly to rotate so as to exchange positions.

[0007] For example, the filling equipment further includes a bottle body feeding device and a bottle cap feeding device. The bottle body feeding device includes a bottle body receiving component and a bottle body conveying component. The bottle body receiving component is used to receive the bottle body, and the bottle body conveying component is used to convey the bottle body on the bottle body receiving component to the placement component. The placement component is used to place the bottle body. When the pipetting device is in the first working state, the other of the first pipetting component and the second pipetting component is used to inject the liquid inside into the bottle body on the placement component. The bottle cap feeding device includes a bottle cap receiving component for receiving bottle caps. The bottle cap can be closed onto the bottle body on the placement component to form a bottle body.

[0008] For example, the bottle receiving assembly includes a bottle receiving component and a bottle sealing component. The bottle receiving component has a plurality of bottle receiving notches arranged sequentially along a predetermined direction. The bottle sealing component is disposed on one side of the bottle receiving notches. The bottle sealing component is used to keep the bottle receiving notches open to receive bottles, or to seal the bottle receiving notches to block the bottles on the bottle receiving notches. The bottle conveying assembly is used to convey the bottles sealed on the bottle receiving notches to the placement component.

[0009] For example, the bottle receiving assembly further includes a bottle driving member for driving the bottle receiving member to move along the predetermined direction so that the plurality of bottle receiving notches are in the open state one by one.

[0010] For example, the bottle cap feeding device further includes a cap fitting assembly for fitting the bottle cap on the bottle cap receiving assembly onto the bottle body on the placement member to form the bottle body.

[0011] For example, the placement device is a turntable, which has four rotatable stations for placing multiple bottles respectively. The first of the four stations is used to receive the bottles. When the pipetting device is in the first working state, the other of the first pipetting component and the second pipetting component is used to inject the liquid inside into the bottle located at the second of the four stations. The bottle cap is used to cover the bottle body located at the third of the four stations to form a bottle. The conveying device is used to receive the bottle located at the fourth of the four stations.

[0012] For example, the detection positions include a labeling detection position and a coding detection position arranged sequentially along the conveying direction, the defects include labeling defects and coding defects, the first detection device includes a labeling detection component and a coding detection component, the labeling detection component is used to detect whether the bottle located at the labeling detection position has the labeling defect, and the coding detection component is used to detect whether the bottle located at the coding detection position has the coding defect.

[0013] For example, the bottle body includes a bottle body and a cap that covers the bottle body. The filling equipment further includes a conveying device and a second detection device. The second detection device has a detection station. The conveying device is used to move the bottle body on the placement object to the detection station and to move the bottle body located at the detection station to the conveying device. The second detection device is used to detect whether the cap of the bottle body located at the detection station is closed to the bottle body.

[0014] For example, the filling equipment further includes a receiving device for transporting the bottle located at the receiving position to the unloading position.

[0015] The filling equipment provided in this invention allows the first and second pipetting components to perform different operations. For example, the first pipetting component can perform aspiration, while the second pipetting component can perform dispensing. This configuration allows the pipetting device to perform multiple operations simultaneously, thereby improving pipetting efficiency. Especially for aspiration and dispensing operations, which have relatively long and roughly equal processing times, the first and second pipetting components can alternate positions, allowing for more synchronized aspiration and dispensing operations. Based on this, the timing of tip replacement for the first and second pipetting components is also roughly the same. Thus, the first and second pipetting components can also change tips within the same timeframe. Furthermore, since the liquid enters the conveying device only after pipetting, the filling equipment can improve work efficiency, thereby increasing the filling throughput to better meet user needs. In addition, the filling equipment has a high degree of automation and good continuity, thereby reducing labor costs and improving work efficiency and accuracy.

Detailed Implementation

[0026] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0027] Embodiments of the present invention provide a filling apparatus. The filling apparatus can perform filling and other related operations on containers such as bottles. The filling apparatus of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-2 As shown, the filling equipment may include a container 1000, a pipetting device 2000, a conveying device 3000, and a first detection device 4000.

[0029] The holder 1000 can be used to hold a bottle. The bottle typically includes a body and a cap that closes to the body. The cap can be attached to the bottle body by any suitable method, such as screwing or plugging. The bottle body may have a cavity for containing liquid (e.g., a pharmaceutical solution or a liquid to be tested). The cap closing onto the bottle body prevents the liquid in the cavity from leaking out. The structure of the holder 1000 can be arbitrary, including but not limited to a support or a tray.

[0030] The pipetting apparatus 2000 may include a first pipetting assembly 2100, a second pipetting assembly 2200, a tip supply assembly 2300, a tip storage box 2400, and a stock solution supply assembly 2500. The tip supply assembly 2300 can be used to store unused pipette tips (e.g., TIP tips). The tip storage box 2400 can be used to store used pipette tips. The stock solution supply assembly 2500 can be used to store liquids. Exemplarily, the stock solution supply assembly 2500 may include a cooler for cooling the liquid within it. The cooler ensures that the liquid within the stock solution supply assembly 2500 is maintained at a lower temperature, thereby extending the liquid's storage time and preventing liquid deterioration.

[0031] The first pipetting assembly 2100 and the second pipetting assembly 2200 may each be equipped with a pipette tip for aspirating liquid and then injecting the liquid into a bottle. Specifically, the first pipetting assembly 2100 and the second pipetting assembly 2200 may each include one or more pipettes. Each pipette may be equipped with a pipette tip for aspirating and injecting liquid. In the embodiment shown in the figure, the first pipetting assembly 2100 and the second pipetting assembly 2200 may each include four pipettes. Each pipette can move vertically for operation. The pipetting device 2000 may have a first operating state and a second operating state. When the pipetting device 2000 is in the first operating state, one of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to aspirate liquid from the mother liquor supply assembly 2500, and the other of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to inject the liquid into a bottle on the container 1000. When the pipetting apparatus 2000 is in its second operating state, one of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to mount pipette tips on the tip supply assembly 2300, and the other of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to discard the pipette tips thereon into the tip storage box 2400. By replacing the pipette tips, contamination between different liquids in the first pipetting assembly 2100 and the second pipetting assembly 2200 can be prevented.

[0032] The conveying device 3000 can be used to receive the filled bottles from the placement piece 1000. Furthermore, the conveying device 3000 can sequentially convey the received bottles to the detection position and the receiving position along the conveying direction. The conveying device 3000 includes, but is not limited to, a belt conveyor or a chain conveyor. The conveying direction can be a straight line or a circular direction, etc.

[0033] The first detection device 4000 can be used to detect whether a bottle located at the detection position has defects. The defects include, but are not limited to, defects such as the liquid level in the bottle not meeting requirements or bottle breakage.

[0034] In practical applications, the filling equipment allows the bottle to be placed on the holder 1000 manually or using a device. Then, the pipetting device 2000 can be in its first operating state. Thus, one of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to aspirate liquid from the mother liquor supply assembly 2500, and the other can be used to inject the liquid into the bottle on the holder 1000. In this way, while the first pipetting assembly 2100 is performing aspiration, the second pipetting assembly 2200 is performing injection. After this operation is completed, the first pipetting assembly 2100 and the second pipetting assembly 2200 can alternate positions, with the second pipetting assembly 2200 performing aspiration and the first pipetting assembly 2100 performing injection. After the first pipetting assembly 2100 and the second pipetting assembly 2200 have completed a predetermined number of aspiration and injection operations, the pipette tip needs to be replaced. When a pipette tip needs to be replaced, the pipetting device 2000 can switch to a second operating state. In this state, one of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to install pipette tips on the tip supply assembly 2300, and the other of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to discard pipette tips into the tip storage box 2400. Thus, the first pipetting assembly 2100 and the second pipetting assembly 2200 can perform tip discarding operations alternately. Furthermore, after the first pipetting assembly 2100 and the second pipetting assembly 2200 have completed the tip discarding operation, they can begin installing pipette tips. At this time, the latter of the first pipetting assembly 2100 and the second pipetting assembly 2200 can perform tip discarding operations. When both the first pipetting assembly 2100 and the second pipetting assembly 2200 have new pipette tips installed, the pipetting device 2000 can switch back to the first operating state. Then, the first pipetting assembly 2100 and the second pipetting assembly 2200 can perform liquid aspiration and dispensing operations again. After the bottle on the placement piece 1000 has been dispensed, it can be transferred to the conveying device 3000. The conveying device 3000 can then convey the bottle to the detection position. At this time, the first detection device 4000 can be used to detect whether the bottle has defects. When the bottle has defects, the filling equipment can mark it or reject it directly. After the first detection device 4000 has completed its detection, the conveying device 3000 can convey the bottle to the receiving position. Then, the bottle can be unloaded manually or by relevant equipment.

[0035] In summary, the filling equipment provided in this embodiment of the invention allows the first pipetting assembly 2100 and the second pipetting assembly 2200 to perform different operations. For example, the first pipetting assembly 2100 can perform aspiration, while the second pipetting assembly 2200 can perform dispensing. This configuration allows the pipetting device 2000 to perform multiple operations simultaneously, thereby improving pipetting efficiency. Especially for aspiration and dispensing operations, which have relatively long and roughly equal processing times, the first pipetting assembly 2100 and the second pipetting assembly 2200 can alternate positions, allowing for more synchronized aspiration and dispensing operations. Based on this, the timing for changing pipette tips for the first pipetting assembly 2100 and the second pipetting assembly 2200 is also roughly the same. Thus, the first pipetting assembly 2100 and the second pipetting assembly 2200 can also change pipette tips within the same time period. Furthermore, since the liquid enters the conveying device 3000 only after pipetting, the filling equipment can improve its efficiency, thereby increasing the filling throughput to better meet user needs. Furthermore, the filling equipment has a high degree of automation and good continuity, which can reduce labor costs and improve work efficiency and accuracy.

[0036] Exemplarily, the pipetting apparatus 2000 may further include a pipetting body and a rotary drive. The pipetting body may be fixed to other components. The rotary drive may be disposed on the pipetting body. The first pipetting assembly 2100 and the second pipetting assembly 2200 may be disposed opposite to each other. The first pipetting assembly 2100 and the second pipetting assembly 2200 may be respectively connected to the drive end of the rotary drive. The rotary drive may be used to drive the first pipetting assembly 2100 and the second pipetting assembly 2200 to rotate and exchange positions. The rotary drive includes, but is not limited to, a motor or a rotary cylinder. With this configuration, the pipetting apparatus 2000 has a high degree of automation, thereby improving work efficiency and throughput. Furthermore, since the pipetting apparatus 2000 can be equipped with only one rotary drive, its structure is relatively simple and its energy consumption is low. Also, the first pipetting assembly 2100 and the second pipetting assembly 2200 can rotate synchronously, thus preventing them from colliding with each other.

[0037] For example, such as Figure 1-4As shown, the filling equipment may further include a bottle loading device 5000 and a cap loading device 6000. The bottle loading device 5000 may include a bottle receiving assembly 5100 and a bottle conveying assembly 5200. The bottle receiving assembly 5100 can be used to receive bottles. Exemplarily, the bottle loading device 5000 may also include a bottle supply assembly 5300. Bottles can be placed within the bottle supply assembly 5300. A vibratory feeder may be provided within the bottle supply assembly 5300 to dispensing the bottles one by one. The bottle receiving assembly 5100 can receive the bottles within the bottle supply assembly 5300. The bottle conveying assembly 5200 can be used to convey the bottles from the bottle receiving assembly 5100 to the placement member 1000. The bottle conveying assembly 5200 includes, but is not limited to, a gripper assembly or a suction cup assembly. The placement member 1000 can be used to place the bottles. When the pipetting device 2000 is in the first working state, the other of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to inject the liquid inside into the bottle on the container 1000.

[0038] The bottle cap feeding device 6000 may include a bottle cap receiving assembly 6100. The bottle cap receiving assembly 6100 is used to receive bottle caps. Exemplarily, the bottle cap feeding device 6000 may also include a bottle cap supply assembly 6300. Bottle caps can be placed within the bottle cap supply assembly 6300. A vibratory feeder may be provided within the bottle cap supply assembly 6300 to dislodge the bottle caps one by one. The bottle cap receiving assembly 6100 can receive the bottle caps within the bottle cap supply assembly 6300. The bottle caps can be fitted onto the bottle body on the container 1000 to form a bottle body. This configuration enriches the functionality of the filling equipment to better meet user needs.

[0039] For example, such as Figure 3As shown, the bottle receiving assembly 5100 may include a bottle receiving member 5110 and a bottle sealing member 5120. The bottle receiving member 5110 may have multiple bottle receiving notches 5111, such as two, three, or more. The multiple bottle receiving notches 5111 may be arranged sequentially along a predetermined direction. The predetermined direction is typically a straight line within the horizontal direction. Each bottle receiving notch 5111 can be used to receive a bottle. The bottle can move to the bottle receiving notch 5111. The bottle sealing member 5120 may be disposed on one side of the bottle receiving notch 5111. The bottle sealing member 5120 includes, but is not limited to, a sealing plate or a sealing strip. The bottle sealing member 5120 can be used to keep the bottle receiving notch 5111 open to receive the bottle. The open bottle receiving notch 5111 can be aligned with the outlet of the bottle supply assembly 5300 to receive the bottle supplied by the bottle supply assembly 5300. Alternatively, the bottle sealing member 5120 can be used to seal the bottle receiving notch 5111 to prevent the bottle from detaching from it. After the bottle receiving notch 5111 receives a bottle, the bottle sealing member 5120 can seal the notch to prevent the bottle from detaching. The bottle transport assembly 5200 can be used to transport the bottle sealed on the bottle receiving notch 5111 to the placement member 1000. The bottle transport assembly 5200 can transport any number of bottles at once, such as one or more bottles on the bottle receiving notch 5111.

[0040] The bottle can move smoothly onto the bottle receiving notch 5111 without getting stuck. This ensures good stability for the bottle receiving component 5100, providing a solid foundation for the bottle handling component 5200 to handle multiple bottles at once. Furthermore, the bottle receiving component 5100 can receive multiple bottles simultaneously and has a high degree of automation, resulting in high efficiency and increased throughput. Additionally, the bottle receiving component 5100 has a simple structure, low manufacturing cost, and compact size, enabling miniaturization. Moreover, the bottle receiving component 5100 can not only receive bottles but also temporarily store them for transfer, inspection, or other operations. Therefore, the bottle receiving component 5100 offers rich functionality, better applicability, and can meet a wider range of needs.

[0041] For example, such as Figure 3 As shown, the bottle receiving assembly 5100 may further include a bottle driving member (not shown due to angle). The bottle driving member can be used to drive the bottle receiving assembly 5110 to move in a predetermined direction, so that the plurality of bottle receiving notches 5111 can be opened one by one. In this way, the plurality of bottle receiving notches 5111 can be aligned one by one with the outlet of the bottle supply assembly 5300. Specifically, with... Figure 3In the embodiment shown, the upper first bottle receiving notch 5111 can be aligned with the outlet of the bottle supply assembly 5300. When the upper first bottle receiving notch 5111 receives a bottle, the bottle driving member can drive the bottle receiving member 5110 to move, so that the upper second bottle receiving notch 5111 aligns with the outlet of the bottle supply assembly 5300, thereby receiving the bottle. Simultaneously, the bottle sealing member 5120 can seal the upper first bottle receiving notch 5111 to prevent the bottle from detaching. This continues until each bottle receiving notch 5111 receives one bottle, and the bottle sealing member 5120 seals each bottle receiving notch 5111. The bottle receiving member 5110 is moved by the bottle driving member so that the multiple bottle receiving notches 5111 on the bottle receiving member 5110 can receive bottles one by one.

[0042] For example, such as Figure 4 As shown, the bottle cap feeding device 6000 may further include a cap closing assembly 6200. The cap closing assembly 6200 can be used to close the bottle cap from the bottle cap receiving assembly 6100 onto the bottle body on the placement member 1000 to form a bottle body. Of course, the cap closing assembly 6200 can also remove the bottle cap from the bottle body on the placement member 1000. Therefore, the cap closing assembly 6200 can be used for both opening and closing the cap.

[0043] For example, such as Figure 5 As shown, the placement component 1000 can be a turntable. The turntable can have four stations. Each of the four stations can be used to place multiple bottles. The four stations can be arranged sequentially along the circumferential direction of the turntable. The first of the four stations can be used to receive bottles. The bottle body handling assembly 5200 can be used to transport the bottles on the bottle body receiving assembly 5100 to the first of the four stations. Then, the turntable can rotate to rotate the bottle to the second of the four stations. When the pipetting device 2000 is in the first working state, the other of the first pipetting assembly 2100 and the second pipetting assembly 2200 can be used to inject the liquid inside into the bottle (specifically, the bottle body) located at the second of the four stations. Then, the turntable can rotate to rotate the bottle to the third of the four stations. Then, the bottle cap can be capped onto the bottle body located at the third of the four stations by manual operation or by the capping assembly 6200 to form a bottle body. Then, the turntable can rotate to rotate the bottle to the fourth of the four stations. Then, the conveyor 3000 can be used to receive bottles located at the fourth of the four stations. With this configuration, the placement unit 1000 can not only be used to place bottles, but also to cooperate with other devices in corresponding operations. The filling equipment has a high degree of automation and smooth operation.

[0044] For example, such as Figure 2 and 5As shown, the detection positions may include labeling detection positions and coding detection positions. The labeling detection positions and coding detection positions may be sequentially arranged along the conveying direction. Defects may include labeling defects and coding defects. The first detection device 4000 may include a labeling detection component 4100 and a coding detection component 4200. The labeling detection component 4100 can be used to detect whether the bottle located at the labeling detection position has a labeling defect. The labeling detection component 4100 includes, but is not limited to, a vision detection component. In some embodiments, when the conveying device 3000 conveys the bottle to the labeling detection position, the bottle can be rotated by a drive component such as a motor. The labeling detection component 4100 can detect the baseline of the bottle body and the baseline of the label affixed thereon, and then compare the distance between the two baselines with an expected distance to determine whether a labeling defect exists. Exemplarily, the filling equipment may also include a labeling component 4300. When the conveying device 3000 conveys the bottle to the labeling position, the labeling component 4300 can affix a label to the bottle body. The labeling position can be located in front of the labeling detection position along the conveying direction. The labeling component 4300 may include a printer to achieve instant labeling. The coding detection component 4200 can be used to detect whether the bottle located at the coding detection position has coding defects. The coding detection component 4200 includes, but is not limited to, a vision inspection component. Exemplarily, the filling equipment may also include a coding component 4400. When the conveyor 3000 conveys the bottle to the coding position, the coding component 4400 can code the bottle. The labeling position can be located in front of the coding detection position along the conveying direction. This configuration enriches the functionality of the filling equipment, thereby meeting the user's needs.

[0045] For example, such as Figure 1-2 As shown in Figure 5, the filling equipment may further include a conveying device 7000 and a second detection device 8000. The second detection device 8000 has a detection station. The conveying device 7000 can be used to move bottles from the container 1000 to the detection station. The conveying device 7000 can also move bottles located at the detection station to the conveying device 3000. The conveying device 7000 includes, but is not limited to, a gripper device or a suction cup device. The second detection device 8000 can be used to detect whether the bottle cap of the bottle located at the detection station is closed to the bottle body. The second detection device 8000 includes, but is not limited to, a vision detection device. For example, after the conveying device 7000 moves the bottle from the container 1000 to the detection station, the second detection device 8000 can detect the baseline of the bottle body and the baseline of the bottle cap, and then compare the distance between the two baselines with an expected distance to determine whether the bottle cap is closed to the bottle body. Specifically, if the bottle cap is closed to the bottle body, the distance between the two baselines is smaller, therefore the expected distance is smaller. If the distance between the two baselines is greater than the expected distance, it is determined that the cap has not been properly closed to the bottle body. In other words, the cap and the bottle body are not tightly closed.

[0046] For example, such as Figure 1 As shown, the filling equipment may also include a receiving device 9000. After the conveying device 3000 conveys the bottle to the receiving position, the receiving device 9000 can transport the bottle located at the receiving position to the unloading position. The structure of the receiving device 9000 can be arbitrary, including but not limited to grippers or suction cups. In this way, relevant personnel can unload the bottle.

[0047] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0048] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features.
