Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, in particular to a freezing tube filling and capping device. Background Art

[0002] Cryogenic tubes are a type of laboratory consumables used to store biological samples, pharmaceutical preparations and other related items. There are many types of cryogenic tubes, which consist of a tube body and a tube cap. With the continuous development of industrial technology, the production of related pharmaceutical preparations for cryogenic tubes has also adopted automated equipment for filling and sealing. There are many types of cryogenic tubes at present. Some types of cryogenic tubes have smooth tube bodies and no nozzle flanges. In the tube delivery process of such cryogenic tubes, the direction of the nozzle cannot be distinguished, and manual intervention and sorting are required before delivery. In addition, in the current technology, it is impossible to adapt the same equipment to the production of cryogenic tubes of multiple specifications of the same type. In addition, the upper cover in the current technology is mostly a scraping cover mode, that is, in the process of the tube body moving forward, the tube mouth scrapes the tube cap down to the tube mouth, and then corrects it through a press capping, which wastes labor time and has a cumbersome structure.

[0003] For example, Chinese patent CN219192618U, published on June 16, 2023, discloses a cryotube decapping, filling, and capping machine, characterized by comprising a tube-handling oscillating hopper fixed to the top of a tube-handling base, a bottle-feeding screw for conveying cryotubes provided on one side of the tube-handling oscillating hopper, a bottle-feeding dial provided on the rear side of the bottle-feeding screw, a directional conveyor belt provided on the rear side of the bottle-feeding screw, and cryotubes conveyed by the bottle-feeding screw being transferred to the bottle-feeding screw via the bottle-feeding dial; a filling head support provided on the rear side of the bottle-feeding screw, a plurality of filling heads provided on the front side of the filling head support, the filling heads provided above the cryotubes, a plurality of capping heads provided above the filling heads, and the bottle-feeding dial, the filling head support, and the directional conveyor belt all fixed to the top of the machine base.

[0029] The specific implementation of the present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] Embodiment one:

[0031] A freezing tube filling and capping device, such as Figure 1 and Figure 2As shown, the device includes a frame 1, on which are mounted a cryopreservation tube parallel body oscillating hopper 2, a tube body oscillating hopper 3, and a tube cap oscillating hopper 10. The tube body oscillating hopper 3 is docked with a flipping and loading mechanism 4, and the tube cap oscillating hopper 10 is docked with a capping mechanism 11. The frame 1 is also equipped with a multi-station turntable 504 mechanism 5, a filling mechanism 12, a clamping mechanism 9, a capping mechanism 8, a waste rejection mechanism 7, and a discharge mechanism 6. The filling mechanism 12, the clamping mechanism 9, the capping mechanism 8, the waste rejection mechanism 7, and the discharge mechanism 6 are arranged clockwise around the multi-station turntable 504 mechanism 5. The tube outlet of the flipping and loading mechanism 4, the lower cap opening of the capping mechanism 11, the pump needle of the filling mechanism 12, the capping head of the capping mechanism 8, the discharge opening of the waste rejection mechanism 7, and the discharge opening of the discharge mechanism 6 correspond to the slots of the turntable 504 of the multi-station turntable 504 mechanism 5 at specific angles.

[0032] The multi-station turntable 504 mechanism 5 includes a turntable 504 with notches evenly distributed around its perimeter. The turntable 504 is connected to a first rotating shaft 502, which is positioned within a first support column 503. The end of the first rotating shaft 502 is connected to a first servo motor 501. A turntable base 505 is concentrically mounted on the outer ring of the turntable 504. The turntable base 505 fits snugly within the turntable 504, but is not a complete circle and has a notch. The turntable base 505 is secured to the frame 1 via support rods 508. A first detection element 506 is positioned on the turntable base 505 at a location corresponding to the outlet of the flip loading mechanism 4. A fixing slot is defined between the loading base and the turntable 504. A turntable washer 507 is quickly mounted on the turntable base 505 and positioned within the fixing slot. By replacing the turntable gasket 507, the height of the pipe openings of pipes of different specifications and lengths can be adjusted to be consistent, so that the equipment can adapt to the production of pipes of different specifications and lengths.

[0033] The flip loading mechanism 4 includes a flip mounting seat 411, which is connected to one end of the first horizontal plate 405. The other end of the first horizontal plate 405 is connected to the second support column 403. First bearings 402 are provided at both ends of the second support column 403, and a second rotating shaft 404 is provided therein. The second rotating shaft 404 is connected to the first bevel gear 406 at one end and to the second servo motor 401 at the other end. A second bearing 408 is provided in the flip mounting seat 411, and a driven shaft 409 is assembled through the second bearing 408. One end of the driven shaft 409 is connected to the second bevel gear 407, and the second bevel gear 407 is meshed with the first bevel gear 406. The other end of the driven shaft 409 is connected to a flip limiter 410, to which a flip limiter outer lining 417 is connected. A flip cavity lining 418 is also connected to the inner cavity of the flip mounting seat 411. The two have different specifications and can be combined and replaced to adapt to the production of pipes of different specifications and lengths. A guide sleeve 412 is connected to the discharge port of the flip mount 411. A seventh air cylinder 413 is located at the inlet of the flip mount 411. A second, adjustable detection element 416 is also located on the flip mount 411, and a third, adjustable detection element 415 is also located on the flip mount end cap 414. These detection elements can be installed in different positions to detect pipes of varying lengths and specifications.

[0034] A fourth cylinder 901 is provided at the bottom of the clamping mechanism 9, and the fourth cylinder 901 is hinged to one end of the first lever 902. The first lever 902 is connected to one end of the third rotating shaft 903, and the other end of the third rotating shaft 903 is connected to the second lever 904. The end of the second lever 904 is hinged with a clamping block 905, and the end of the clamping block 905 is provided with a silicone pad 906.

[0035] The reject mechanism 7 comprises a guide sleeve 705, within which is concentrically mounted a reject lift rod 702. A removable extension rod 703 is attached to the top of the lift rod 702, allowing replacement for tubes of varying heights. The end of the lift rod 702 is connected to a fifth cylinder 701. A sixth cylinder 704 is located behind the outlet of the guide sleeve 705, ejecting defective products. A waste hopper 706 is connected to the outlet of the guide sleeve 705 to receive defective products.

[0036] The discharging mechanism 6 includes a discharging frame plate 601 , which is connected to the discharging chute 602 by a quick release method.

[0037] During the specific operation, the parallel tube body oscillating bucket 2 is first used to arrange the tube body, and the tube body is transported to the tube body oscillating bucket 3. After being arranged by the tube body oscillating bucket 3, it is transported to the flipping feeding mechanism 4. The flipping feeding mechanism 4 identifies the direction of the tube mouth of the tube body, and after the flipping process, the tube mouth of the tube body is transported upward to the corresponding turntable 504 slot on the multi-station turntable 504 mechanism 5. When the first detection element 506 located there detects that the tube body is in place, the turntable 504 rotates and drives the tube body to the filling station. The filling mechanism 12 descends and the pump needle penetrates into the interior of the tube body for filling. As the liquid level rises, the filling mechanism 12 rises synchronously to maintain the height difference between the pump needle and the liquid level. After the filling is completed, the filling mechanism 12 drives the pump needle to rise, and the turntable 504 transports the tube body to the capping station. The capping mechanism 11 secures the tube cap to the tube body. The turntable 504 then transports the tube body to the capping station. The fifth cylinder 701 of the clamping mechanism 9 extends, ultimately driving the second lever 904 to rotate, causing the pressing block 905 to compress the tube body. The capping mechanism 8 then lowers the capping head, pressing and rotating the tube cap, tightening the cap to the tube body. After this operation is complete, the capping mechanism 8 and clamping mechanism 9 return to their original positions. The turntable 504 transports the tube body to the reject station. The capping servo feedback torque data indicates whether the capping is acceptable. If not, the sixth cylinder 704 of the reject mechanism 7 activates, driving the defective product down. This sixth cylinder 704 then ejects the defective product, which falls into the waste hopper 706. If the capping is acceptable, the turntable 504 transports the finished product to the discharge station. The combined forces of the turntable 504 and the discharge rack 601 force the finished product into the discharge chute 602, completing the discharge process.

[0038] This solution enables the production of multiple cryotubes of the same type and specifications by simply replacing the turntable gasket 507. This solution not only accommodates the automated production of cryotubes with orifice flanges, but also of those without, eliminating the need for manual intervention and reducing potential contamination during the production process. A reject mechanism 7 removes defective products, eliminating the need for manual inspection.

[0039] Example 2:

[0040] The device includes a frame 1, on which are mounted a parallel body oscillating hopper 2 for cryopreservation tubes, a body oscillating hopper 3, and a cap oscillating hopper 10. The body oscillating hopper 3 is docked with a flipping and loading mechanism 4, while the capping and punching mechanism 11 is docked with the capping and punching mechanism 10. The frame 1 also includes a multi-station turntable 504 mechanism 5, a filling mechanism 12, a clamping mechanism 9, a capping mechanism 8, a waste rejection mechanism 7, and a discharge mechanism 6. These three mechanisms are arranged clockwise around the multi-station turntable 504 mechanism 5. The tube outlet of the flipping and loading mechanism 4, the lower cap opening of the capping and punching mechanism 11, the pump needle of the filling mechanism 12, the capping head of the capping mechanism 8, the discharge opening of the waste rejection mechanism 7, and the discharge opening of the discharge mechanism 6 correspond to the notches of the turntable 504 of the multi-station turntable 504 mechanism 5 at specific angles.

[0041] The multi-station turntable 504 mechanism 5 includes a turntable 504 with notches evenly distributed around its perimeter. The turntable 504 is connected to a first rotating shaft 502, which is positioned within a first support column 503. The end of the first rotating shaft 502 is connected to a first servo motor 501. A turntable base 505 is concentrically mounted on the outer ring of the turntable 504. The turntable base 505 fits snugly within the turntable 504, but is not a complete circle and has a notch. The turntable base 505 is secured to the frame 1 via support rods 508. A first detection element 506 is positioned on the turntable base 505 at a location corresponding to the outlet of the flip loading mechanism 4. A fixing slot is defined between the loading base and the turntable 504. A turntable washer 507 is quickly mounted on the turntable base 505 and positioned within the fixing slot. By replacing the turntable gasket 507, the height of the pipe openings of pipes of different specifications and lengths can be adjusted to be consistent, so that the equipment can adapt to the production of pipes of different specifications and lengths.

[0042] The flip loading mechanism 4 includes a flip mounting seat 411, which is connected to one end of the first horizontal plate 405. The other end of the first horizontal plate 405 is connected to the second support column 403. First bearings 402 are provided at both ends of the second support column 403, and a second rotating shaft 404 is provided therein. The second rotating shaft 404 is connected to the first bevel gear 406 at one end and to the second servo motor 401 at the other end. A second bearing 408 is provided in the flip mounting seat 411, and a driven shaft 409 is assembled through the second bearing 408. One end of the driven shaft 409 is connected to the second bevel gear 407, and the second bevel gear 407 is meshed with the first bevel gear 406. The other end of the driven shaft 409 is connected to a flip limiter 410, to which a flip limiter outer lining 417 is connected. A flip cavity lining 418 is also connected to the inner cavity of the flip mounting seat 411. The two have different specifications and can be combined and replaced to adapt to the production of pipes of different specifications and lengths. A guide sleeve 412 is connected to the discharge port of the flip mount 411. A seventh air cylinder 413 is located at the inlet of the flip mount 411. A second, adjustable detection element 416 is also located on the flip mount 411, and a third, adjustable detection element 415 is also located on the flip mount end cap 414. These detection elements can be installed in different positions to detect pipes of varying lengths and specifications.

[0043] A fourth cylinder 901 is provided at the bottom of the clamping mechanism 9, and the fourth cylinder 901 is hinged to one end of the first lever 902. The first lever 902 is connected to one end of the third rotating shaft 903, and the other end of the third rotating shaft 903 is connected to the second lever 904. The end of the second lever 904 is hinged with a clamping block 905, and the end of the clamping block 905 is provided with a silicone pad 906.

[0044] The reject mechanism 7 comprises a guide sleeve 705, within which is concentrically mounted a reject lift rod 702. A removable extension rod 703 is attached to the top of the lift rod 702, allowing replacement for tubes of varying heights. The end of the lift rod 702 is connected to a fifth cylinder 701. A sixth cylinder 704 is located behind the outlet of the guide sleeve 705, ejecting defective products. A waste hopper 706 is connected to the outlet of the guide sleeve 705 to receive defective products.

[0045] The discharging mechanism 6 includes a discharging frame plate 601 , which is connected to the discharging chute 602 by a quick release method.

[0046] The capping mechanism 11 includes a capping mounting base 1101, which is internally provided with a chute. A first capping clamping plate 1103 and a second capping clamping plate 1106 can slide and close within the chute. The first and second capping clamping plates 1103 and 1106 are respectively connected to a first cylinder 1102 and a second cylinder 1107 to provide power. A third cylinder 1105 is connected above the lower capping opening of the capping mounting base 1101 to provide power for capping. The end of the rod of the third cylinder 1105 is connected to a capping head 1104.

[0047] During the specific operation, the tube body is first arranged by the parallel tube body oscillating hopper 2 and transported to the tube body oscillating hopper 3. After being arranged by the tube body oscillating hopper 3, the tube body is transported to the flipping and loading mechanism 4. The flipping and loading mechanism 4 identifies the direction of the tube body's nozzle. After flipping, the tube body is transported upward to the corresponding notch of the turntable 504 on the multi-station turntable mechanism 5. When the first detection element 506 located there detects that the tube body is in place, the turntable 504 rotates, driving the tube body to the filling station. The filling mechanism 12 descends, pushing the pump needle deeper into the tube body for filling. As the liquid level rises, the filling mechanism 12 rises synchronously, maintaining the height difference between the pump needle and the liquid level. After filling is completed, the filling mechanism 12 drives the pump needle to rise, and the turntable 504 transports the tube body to the capping station. At this time, the first cylinder 1102 and the second cylinder 1107 of the capping mechanism 11 extend, driving the first capping clamping plate 1103 and the second capping clamping plate 1106 to clamp the tube body. At the same time, the second capping clamp 1106 pushes the tube cap into the circular cavity formed by the first and second capping clamps 1103 and 1106. The third cylinder 1105 then extends, and the capping head 1104 presses the tube cap onto the tube body. After completing this operation, the capping mechanism 11 resets, the turntable 504 conveys the tube body to the capping station, and the fifth cylinder 701 of the clamping mechanism 9 extends, ultimately driving the second lever 904 to rotate, causing the pressing block 905 to compress the tube body. The capping mechanism 8 then drives the capping head down, compressing the tube cap and rotating it, tightening the cap to the tube body. After this operation is complete, the capping mechanism 8 and the clamping mechanism 9 reset, and the turntable 504 conveys the tube body to the reject station. The torque data fed back by the capping servo indicates whether the capping is qualified. If not, the sixth cylinder 704 of the reject mechanism 7 activates, driving the defective product down. The sixth cylinder 704 then actuates to eject the defective product, which falls into the waste hopper 706. If the capping is qualified, the turntable 504 transports the finished product to the discharging station. Under the joint force of the turntable 504 and the discharging rack plate 601, the finished product is forced into the discharging chute 602 to complete the discharging action.

[0048] This solution has a capping mechanism 11 with centering, which keeps the tube body and the tube cap concentric before capping, thereby ensuring the success rate of capping while saving costs and working hours.

[0049] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
