Description

Technical Field

[0001] This utility model relates to a suction bottle device for multi-channel diversion, belonging to the field of medical product technology. Background Technology

[0002] In automated production lines for medical products, the sorting and removal of defective products after the light inspection process is a crucial step in ensuring product quality. Traditional rejection devices mainly use cylinder-driven push rods for sorting, but this method is prone to instability and inaccuracy due to factors such as air pressure and product slippage on the production line, resulting in a high false rejection rate and requiring manual re-inspection, increasing production costs. Currently, to adapt to high-speed production lines, the method of removing bottles by negative pressure adsorption is gradually becoming more common. However, existing negative pressure adsorption sorting devices rely on only a single negative pressure air path. Due to poor sealing between adjacent air paths, air leakage can occur, causing negative pressure gas to leak into other idle air paths. This can lead to lightweight, qualified products being mistakenly removed from the workstation, resulting in false adsorption or even scratching of the bottle. Furthermore, it only removes the bottle by cutting off the negative pressure, but there may be vacuum residue, causing the bottle to remain or detach delayed, affecting the production line cycle. Therefore, researching a new type of bottle suction device for multi-channel diversion is of great practical significance. Summary of the Invention

[0007] Furthermore, a sealing gasket is provided between the mounting plate and the star wheel disk, and the sealing gasket has several air holes that correspond to the number of the first air channels. The air holes are connected to the openings of the first air channels on the lower surface of the star wheel disk.

[0008] Furthermore, the grooves are divided into several groups, and the number of grooves in each group and the number of air path switching components are equal to the number of arc-shaped air slots opened on the upper surface of the air distribution plate. The outlet of each air path switching component is connected to one arc-shaped air slot through a pipeline and an air inlet. When the star wheel rotates, each arc-shaped air slot can be connected to at most one groove at the same time.

[0009] Furthermore, the air inlets are staggered so that they are in different radial directions; the first air passages corresponding to each set of grooves are staggered between the openings on the lower surface of the star disk so that the openings are in different radial directions.

[0021] Example

[0022] like Figures 1-4 As shown in Figures 8 and 10, this utility model provides a bottle suction device for multi-channel diversion, including: a fixed base 1, in which a rotating shaft 2 is rotatably provided; the fixed base 1 is installed on one side of the production line, and the rotating shaft 2 is fixed inside the fixed base 1 by means of a bearing. A drive assembly, the output shaft of which is connected to the rotating shaft 2 and drives the rotating shaft 2 to rotate; The gas path control unit includes at least one gas path switching component 3. The gas path switching component 3 has a first inlet 31, a second inlet 32, and an outlet 33. The first inlet 31 is connected to a negative pressure generating mechanism, and the second inlet 32 ​​is connected to a positive pressure generating mechanism. The gas path switching component 3 is configured to control the connection between the first inlet 31 and the outlet 33 or the connection between the second inlet 32 ​​and the outlet 33. It should be noted that the gas path switching component 3 is preferably a solenoid valve. The negative pressure generating mechanism is a vacuum pump, and the positive pressure generating mechanism is a compressor. The positive pressure is less than the negative pressure, preferably 0.3-0.5 times the negative pressure, to ensure that the negative pressure is successfully adsorbed while avoiding the positive pressure affecting the transport posture of other bottles on the production line. Since the negative pressure generating mechanism and the positive pressure generating mechanism are devices known to those skilled in the art, they are not shown in the accompanying drawings. The specific layout of the gas path control unit can be freely arranged by those skilled in the art according to the needs of the function and production space, and will not be elaborated here. Preferably, a pressure regulating valve is provided on the positive pressure pipeline to adjust the positive pressure gas path pressure within a small pressure range.

[0023] The bottle suction execution unit includes a star wheel disk 4 connected to the rotating shaft 2 and rotating synchronously with the rotating shaft 2. The star wheel disk 4 has a plurality of grooves 41 evenly arranged around its periphery for accommodating bottles. The star wheel disk 4 has a plurality of first air passages 42 corresponding to the number of grooves 41 inside its interior. One end of each first air passage 42 is connected to the corresponding groove 41, and the other end is connected to the lower surface of the star wheel disk 4. The air distribution plate 5 is installed inside the fixed base 1 by several sets of elastic support components and is located below the star wheel disk 4. Preferably, three sets of elastic support components are evenly arranged circumferentially. These elastic support components apply an axial preload to the air distribution plate 5 so that the upper surface of the air distribution plate 5 abuts against the lower surface of the star wheel disk 4, achieving a sealed contact to ensure airtightness when the air passage is opened or closed, avoiding air leakage. The upper surface of the air distribution plate 5 has several arrayed arc-shaped air grooves 51 arranged radially. Each arc-shaped air groove 51 is connected to an air inlet 52, which is connected to the outlet 33 of the air passage switching component 3 via a pipe. It should be noted that the arc-shaped air grooves 51 do not penetrate the upper and lower surfaces of the air distribution plate 5. Figure 8 As shown, "arranged in a radial array" means that the starting and ending ends of each arc-shaped air groove 51 are located in the same radial direction, and the spacing between adjacent arc-shaped air grooves 51 is equal; the air inlet 52 is connected to the outlet 33 of the air path switching component 3 through a pipeline, and then connected to the positive pressure generating mechanism or the negative pressure generating mechanism. The pipeline is preferably a rubber hose. Since the setting of the pipeline is common knowledge to those skilled in the art, it is not shown in the figure; when the driving component drives the star wheel disk 4 to rotate, the air distribution plate 5 is fixed, and the lower surface of the star wheel disk 4 and the upper surface of the air distribution plate 5 rotate and rub against each other, so that the opening of the first air passage 42 on the lower surface of the star wheel disk 4 is connected to the arc-shaped air groove 51 in sequence to form a gas passage or misaligned with the arc-shaped air groove 51 to form a gas disconnection.

[0024] First, through the above settings, this application achieves multi-channel diversion, which can accurately reject products with unqualified liquid levels and appearances to specific production lines. This solves the problem of unstable rejection and displacement of qualified products caused by product slippage when kicking out unqualified products by cylinders. Second, under the premise of achieving multi-channel diversion, by setting the positive and negative pressure and the coordinated cooperation of the air path switching component 3, a dynamic switching mechanism for anti-gas leakage is achieved. This can eliminate gas leakage interference between the arc-shaped air grooves 51, effectively improving rejection stability and rejection accuracy. When it is necessary to adsorb the bottle, the air path switching component 3 controls the connection of negative pressure so that the bottle is adsorbed in the groove 41. When it is not necessary to adsorb the bottle, the air path switching component 3 controls the connection of positive pressure to avoid accidental adsorption. Or when the bottle suction device is running to the release position, the air path switching component 3 controls the connection of positive pressure, and the positive pressure airflow pushes the bottle away from the groove 41 to avoid the problem of incomplete bottle release.

[0025] Specifically, such as Figure 2 , 3As shown in Figures 5 and 6, a mounting plate 6 and a friction disk 7 are coaxially arranged below the star wheel disk 4, rotating synchronously with the star wheel disk 4. The upper surface of the mounting plate 6 abuts against the lower surface of the star wheel disk 4, and the upper surface of the friction disk 7 abuts against the lower surface of the mounting plate 6. The mounting plate 6 and the friction disk 7 are perforated with a plurality of second air passages 8 corresponding to the number of the first air passages 42. The second air passages 8 are connected one-to-one with the openings of the first air passages 42 on the lower surface of the star wheel disk 4. The elastic support assembly applies an axial preload to the air distribution plate 5 so that the upper surface of the air distribution plate 5 abuts against the lower surface of the friction disk 7. Understandably, with this setup, positive or negative pressure enters the arc-shaped air groove 51 through the air inlet 52, and then, during the rotation of the star wheel 4, sequentially enters the corresponding groove 41 through the second air passage 8 and the first air passage 42. This setup effectively extends the service life, reduces maintenance costs, and ensures the air passage sealing between the friction contact surfaces under long-term rotational friction, further preventing air leakage between the arc-shaped air grooves 51. Preferably, the ring width of the friction disc 7 is 0.4-0.5 times the ring width of the mounting plate 6. This setup significantly reduces the friction area, lowers the difficulty of controlling the air passage sealing between the friction contact surfaces, and reduces the cost of replacement later.

[0026] Specifically, such as Figure 2 , 7 As shown, the rotating shaft 2 is provided with a first shoulder 21 and a second shoulder 22. The mounting plate 6 is sleeved on the rotating shaft 2 and fixed above the first shoulder 21 by fastening bolts 9. The friction disc 7 is fixed to the lower surface of the mounting plate 6 by fastening bolts 9. The first shoulder 21 and the second shoulder 22 are integral structures with the rotating shaft 2 through processing. The first shoulder 21 provides support for the mounting plate 6. The star wheel 4 is sleeved on the rotating shaft 2 and abuts against the mounting plate 6. The star wheel 4 at least partially protrudes from the plane of the upper end face of the rotating shaft 2. A pressure block 10 is also provided above the star wheel 4, and a clamping bolt 11 passes through the pressure block 10. The clamping bolt 11 is screwed to the rotating shaft 2. With this arrangement, the contact pressure between the mounting plate 6 and the star wheel 4 can be dynamically adjusted to ensure the air passage sealing between the first air passage 42 and the second air passage 8, so that the gas can be stably transmitted to the corresponding groove 41 position.

[0027] Specifically, such as Figure 2As shown, a sealing gasket 12 is provided between the mounting plate 6 and the star wheel disk 4. The sealing gasket 12 has several air holes that correspond to the number of the first air passages 42. The air holes are connected to the openings of the first air passages 42 on the lower surface of the star wheel disk 4. The sealing gasket 12 is made of rubber. This arrangement can coordinate and compensate for the processing errors between the mounting plate 6 and the star wheel disk 4, further ensure the air circuit sealing, and avoid the risk of air leakage between the mounting plate 6 and the star wheel disk 4.

[0028] Specifically, the groove 41 is divided into several groups. The number of grooves 41 and the number of air path switching components 3 in each group are equal to the number of arc-shaped air grooves 51 opened on the upper surface of the air distribution plate 5. The outlet 33 of each air path switching component 3 is connected to one arc-shaped air groove 51 through a pipeline and an air inlet 52. When the star wheel 4 rotates, each arc-shaped air groove 51 can be connected to at most one groove 41 at the same time. Preferably, three gas path switching components 3 and three arc-shaped air grooves 51 are provided in this application. By independently configuring the gas path switching component 3 for each arc-shaped air groove 51, the gas path switching component 3 can switch according to the sorting sequence. When it is not necessary for all grooves 41 in the same group to be negatively pressure adsorbed and removed, only the arc-shaped air groove 51 that needs to be adsorbed needs to be maintained under negative pressure. Other idle arc-shaped air grooves 51 in the same group are connected to positive pressure. The positive pressure gas forms an air curtain barrier in the corresponding arc-shaped air groove 51, blocking the gas leakage path of the arc-shaped air groove 51 connected to negative pressure. This reduces the load on the overall negative pressure generating mechanism and avoids the problem of negative pressure gas leaking from the current arc-shaped air groove 51 to other idle arc-shaped air grooves 51, causing mis-adsorption or causing the position of other products on the production line to shift, affecting the conveying posture.

[0029] Specifically, to further prevent cross-ventilation, such as Figure 10 As shown, the air inlets 52 are staggered, so that the air inlets 52 are in different radial directions; as Figure 9 As shown, the first air passage 42 corresponding to each set of grooves 41 is staggered between the openings on the lower surface of the star disk 4, so that the openings are in different radial directions. It should be noted that different radial directions mean that the lines connecting them to the center of the circle do not coincide.

[0030] Specifically, such as Figure 2 , 6As shown, the fixed base 1 has a flange 13 arranged circumferentially inside, and a fixed block 14 is fixedly connected to the inner ring of the flange 13. The elastic support assembly includes a guide rod 15 connected to the fixed block 14. The upper end of the guide rod 15 passes through and extends to the upper surface of the air distribution plate 5, and the upper end of the guide rod 15 is located in the gap area between the inner ring of the friction disc 7 and the first shoulder 21. A compression spring 16 is sleeved on the guide rod 15. One end of the compression spring 16 abuts against the lower surface of the air distribution plate 5, and the other end abuts against the upper surface of the fixed block 14. This arrangement ensures that the air distribution plate 5 can move axially, avoiding air leakage and cross-flow caused by the misalignment of the air distribution plate 5, and also absorbs mechanical vibration during operation, reducing the impact of mechanical vibration on the air circuit sealing.

[0031] Specifically, the drive assembly includes a drive motor 17 and a reducer 18. The output shaft of the drive motor 17 is connected to the reducer 18, and the output shaft of the reducer 18 is connected to the rotating shaft 2. The reducer 18 is fixedly installed on the lower surface of the fixed block 14.

[0032] Specifically, such as Figure 4 As shown, the gas path control unit also includes a gas filter 19, which is connected in the pipeline between the outlet 33 of the gas path switching component 3 and the gas inlet 52. It is understood that one end of the gas filter 19 is connected to the outlet 33 of the gas path switching component 3 via a pipeline, and the other end is connected to the gas inlet 52 via a pipeline. The pipeline can be made of materials well known to those skilled in the art, and for ease of viewing other structures, the pipeline is not shown in the accompanying drawings. By providing the gas filter 19, impurities can be filtered during negative pressure adsorption, effectively preventing damage to the gas path switching component 3.

[0033] Specifically, such as Figure 1 As shown, to further ensure adsorption stability, a suction cup 43 is provided in the groove 41, and the air inlet of the suction cup 43 is connected to the first air channel 42.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are exhaustively listed. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these modifications and improvements are all within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims.
