[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0053] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two elements or interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0054] In the description of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0055] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0056] like Figures 1-6 As shown, the present invention provides a star wheel bottle discharging device for transferring products between the two processes of bottle blowing and filling. The star wheel bottle discharging device includes a bottle discharging drive mechanism 1, a star wheel assembly 2, a horizontal drive mechanism 3, a locking assembly 4 and a table 5. The star wheel assembly 2 includes a mounting seat 21 and a star wheel 22. The bottle discharging drive mechanism 1 is arranged below the mounting seat 21. A transfer shaft 221 is provided at the center of the star wheel 22. The transfer shaft 221 can pass through the mounting seat 21 and can be detachably connected to the output end of the bottle discharging drive mechanism 1. The output end of the horizontal drive mechanism 3 is fixedly connected to the mounting seat 21. The horizontal drive mechanism 3 is configured to drive the mounting seat 21 to move between the working position and the maintenance position. When the mounting seat 21 is in the working position, the bottle discharging drive mechanism 1 can drive the transfer shaft 221. It rotates around its own axis so that the product on the star wheel 22 can be transferred from the output end of the bottle blowing machine 100 to the input end of the filling machine 200; the locking assembly 4 includes a locking cylinder 41, a locking rod 42 and a locking seat 43. The locking seat 43 is provided with a locking groove. The locking rod 42 is fixedly connected to the output end of the locking cylinder 41. When the mounting base 21 is in the working position, the locking cylinder 41 can drive the locking rod 42 to be inserted into the locking groove in the vertical direction; the working position, maintenance position, bottle discharge drive mechanism 1 and locking seat 43 are all arranged on the table 5.

[0057] When it is necessary to clean the star wheel 22, first turn off the bottle discharging drive mechanism 1, then separate the adapter shaft 221 from the output end of the bottle discharging drive mechanism 1, the locking cylinder 41 drives the locking rod 42 to separate from the locking groove, and the horizontal drive mechanism 3 drives the mounting seat 21 from the working position to the maintenance position, thereby completing the disassembly of the star wheel 22, greatly improving the efficiency of cleaning the star wheel 22, the action is simple and efficient, the structure is reliable, and it is not easy to be damaged.

[0058] It is understandable that multiple star wheels 22 can be provided according to actual production needs. When one star wheel 22 is performing a cleaning operation, another star wheel 22 can be directly installed on the output end of the bottle discharge drive mechanism 1, thereby shortening the pause time in the production process and increasing output.

[0059] For example, in this embodiment, both the horizontal drive mechanism 3 and the locking cylinder 41 are linear cylinder structures commonly used in the art, and their working principles and specific structures are not described in detail here. In other embodiments, the horizontal drive mechanism 3 and the locking cylinder 41 can also be hydraulic drive structures or oil cylinders, which are not specifically limited here.

[0060] For example, in this embodiment, the bottle discharging drive mechanism 1 is specifically a servo motor commonly used in the art, and a speed reducer is provided at the output end thereof to ensure stable torque output.

[0061] Specifically, the star wheel bottle discharging device also includes a limiting guide assembly 6, which includes a first limiting member 61 and a second limiting member 62. The first limiting member 61 is set in the working position; the second limiting member 62 is set in the maintenance position, and the mounting seat 21 is limited between the working position and the maintenance position. With the above arrangement, the first limiting member 61 and the second limiting member 62 are both detachably connected to the table 5; when the mounting seat 21 is in the working position, it can abut against the first limiting member 61; when the mounting seat 21 is in the maintenance position, it can abut against the second limiting member 62, thereby ensuring the accuracy of the movement of the mounting seat 21 and preventing positional deviation.

[0062] More specifically, the position limiting guide assembly 6 further includes a guide rail 63, which is fixedly mounted on the platform 5, with one end facing the first position limiting member 61 and the other end facing the second position limiting member 62. The mounting base 21 is slidably mounted on the guide rail 63. The provision of the guide rail 63 further ensures the accuracy of the movement of the mounting base 21 and prevents position deviation.

[0063] More specifically, two second position-limiting members 62 and two guide rails 63 are arranged at intervals in the horizontal direction, and the guide rails 63 correspond one to one with the second position-limiting members 62. The above arrangement can improve the stability of the mounting base 21 during movement.

[0064] For example, in this embodiment, the guide rail 63 is linear. In other embodiments, the guide rail 63 can also be adjusted to other shapes as needed, which is not specifically limited here.

[0065] Specifically, a plurality of transfer grooves 220 are provided at intervals along the outer circumference of the star wheel 22, and the products can be inserted into the transfer grooves 220. The provision of the transfer grooves 220 facilitates the transfer of the products.

[0066] More specifically, the star-wheel bottle discharging device further includes a bottle-removing assembly 7, which includes a bottle-removing drive mechanism 71 and a bottle-removing guard plate 72. The bottle-removing guard plate 72 is fixedly connected to the output end of the bottle-removing drive mechanism 71. The bottle-removing guard plate 72 is curved and disposed on the outer periphery of the star wheel 22. Driven by the star wheel 22, products can slide along the bottle-removing guard plate 72. If a product becomes stuck between the star wheel 22 and the bottle-removing guard plate 72, the bottle-removing drive mechanism 71 can drive the bottle-removing guard plate 72 away from the star wheel 22. This arrangement prevents products from becoming stuck between the star wheel 22 and the bottle-removing guard plate 72, thereby preventing the star wheel 22 from experiencing increased resistance and possibly becoming stuck. When the bottle-removing drive mechanism 71 drives the bottle-removing guard plate 72 away from the star wheel 22, the stuck product falls under its own weight, thereby not affecting the transport of other products and improving the yield rate.

[0067] For example, in this embodiment, the bottle-removing drive mechanism 71 is a linear cylinder structure commonly used in the art, and its working principle and specific structure are not described in detail here. In other embodiments, the bottle-removing drive mechanism 71 can also be a hydraulic drive structure or an oil cylinder, which is not specifically limited here.

[0068] In addition, before the mounting seat 21 moves from the working position to the cleaning position, the bottle stripping driving mechanism 71 drives the bottle stripping guard plate 72 to move away from the star wheel 22 , thereby preventing the bottle stripping guard plate 72 from interfering with the mounting seat 21 .

[0069] More specifically, the bottle-removing assembly 7 also includes a torque monitoring mechanism, which is configured to be communicatively connected to the bottle-removing drive mechanism 71 and to measure the output torque of the bottle-removing drive mechanism 1 in real time. The torque monitoring mechanism is preset with a torque threshold. When the output torque of the bottle-removing drive mechanism 1 is greater than or equal to the torque threshold, the torque monitoring mechanism can send a control signal to the bottle-removing drive mechanism 71. The provision of the above-mentioned torque monitoring mechanism can achieve automatic control of the bottle-removing drive mechanism 71, improve automation, and reduce human intervention. In this embodiment, the bottle-removing drive mechanism 71 is specifically a torque sensor commonly used in the art, and its working principle and specific structure are not detailed here.

[0070] Specifically, the star wheel assembly 2 also includes a detection disk 23 and a synchronous detection mechanism 24. The detection disk 23 is disposed on the mounting base 21 and is coaxially arranged with the star wheel 22. The synchronous detection mechanism 24 is fixedly mounted on the table 5 and is capable of measuring the distance between the edge of the detection disk 23 and itself in real time. The synchronous detection mechanism 24 is communicatively connected to the bottle discharge drive mechanism 1. With the above arrangement, during the high-speed rotation of the star wheel 22, the star wheel detection disk 23 and the synchronous detection mechanism 24 cooperate with each other to monitor in real time whether the star wheel 22 is offset from the operating position, thereby preventing the product from accidentally falling during transportation and ensuring the yield rate.

[0071] The present invention also provides a blow-filling system for blow-forming and filling products. The blow-filling system includes a blow-forming machine 100, a filler 200, the aforementioned star-wheel bottle discharging device, and an isolation device 300. The blow-forming machine 100 is configured to blow-form products; the filler 200 is configured to fill products. The star-wheel bottle discharging device operates between the output of the blow-forming machine 100 and the input of the filler 200. The isolation device 300 includes an isolation door 301 that can block the input of the filler 200.

[0072] It is understood that this blow-fill system has all the benefits of the aforementioned star-wheel bottle discharge device, and further details are omitted here. Furthermore, an isolation door 301 can be used to seal the input end of the filling machine 200 to prevent dust from entering the filling machine 200 and contaminating the product during subsequent filling processes during the movement of the mounting base 21 and the replacement of the star wheel 22.

[0073] Specifically, the isolation device 300 also includes an isolation drive mechanism 302, a connecting beam 303, and a door frame structure 304. The connecting beam 303 is fixedly connected to the output end of the isolation drive mechanism 302, and the isolation door 301 is fixedly connected to the connecting beam 303. The isolation drive mechanism 302 can drive the connecting beam 303 to move vertically. The door frame structure 304 is fixedly mounted at the input end of the filling machine 200, and the isolation door 301 is slidably connected to the door frame structure 304. This arrangement enables the isolation door 301 to be opened and closed.

[0074] For example, in this embodiment, the isolation drive mechanism 302 is specifically a linear cylinder structure commonly used in the field, and two isolation drive mechanisms 302 are arranged at intervals in the horizontal direction, and the two ends of the connecting beam 303 are fixedly connected to the output ends of the two isolation drive mechanisms 302 one by one to ensure the stability of the isolation door 301 during the opening and closing process.

[0075] More specifically, a sealing strip 304a is provided at the joint between the door frame structure 304 and the isolation door 301. The provision of the sealing strip 304a can block the gap between the door frame structure 304 and the isolation door 301, further improving the sealing performance.

[0076] More specifically, the stroke of the output end of the isolation drive mechanism 302 extends in the vertical direction. An upper limit switch 305 is provided at the top of the stroke, and a lower limit switch 306 is provided at the bottom of the stroke. Both the upper limit switch 305 and the lower limit switch 306 can measure the vertical distance between their own position and the connecting beam 303, and both are communicatively connected to the isolation drive mechanism 302. The above arrangement can realize automatic control of the opening and closing of the isolation door 301; when the connecting beam 303 approaches the upper limit switch 305, the upper limit switch 305 can shut down the isolation drive mechanism 302 through a control signal; when the connecting beam 303 approaches the lower limit switch 306, the lower limit switch 306 can also shut down the isolation drive mechanism 302 through a control signal; thereby further improving the degree of automation of the overall operation process, reducing manual intervention, and improving operation efficiency.

[0077] For example, in this embodiment, both the upper limit switch 305 and the lower limit switch 306 are photoelectric distance sensors commonly used in the art, and their working principles and specific structures are not described in detail here.

[0078] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
