Description

Technical Field

[0001] This application relates to the field of paper cup production technology, and in particular to a cup dispensing and flipping mechanism. Background Technology

[0002] With the development of paper cup production technology, machines capable of high-speed paper cup production have emerged. High-speed paper cup machines offer advantages such as high efficiency and stable quality, and typically feature multi-station paper cup turrets capable of continuously performing multiple processing steps on the paper cups, thus significantly improving production efficiency. After one rotation cycle on the multi-station paper cup turret, the paper cups need to be demolded from the mold for the next processing operation. The demolding mechanism usually needs not only to smoothly and quickly detach the paper cups along the direction of the mold, but also to have a flipping function to adjust the opening orientation of the paper cups, facilitating subsequent processing operations such as feeding.

[0003] However, in the existing technology, the design of the mechanism for demolding and flipping paper cups is not reasonable enough. The demolding and flipping of paper cups is unstable, the coordination with the multi-station paper cup turret is not good enough, and the short distance after demolding and flipping is not conducive to the flexible layout of other mechanisms. Summary of the Invention

[0004] Therefore, it is necessary to provide a cup dispensing and flipping mechanism to address the problem of reduced paper cup production efficiency caused by the unreasonable design of existing paper cup demolding and flipping mechanisms.

[0005] A cup-dispensing and flipping mechanism for conveying and flipping paper cups includes a frame, a paper cup turret, a flipping assembly, and a demolding assembly. The paper cup turret is rotatably mounted on the frame and has multiple molds for accommodating the paper cups along its circumferential direction. The flipping assembly includes a accommodating member and a fixing member mounted on the frame. The accommodating member is rotatably mounted on the fixing member and has an accommodating hole for accommodating the paper cup. The demolding assembly is slidably disposed between the flipping assembly and the paper cup turret along the radial direction of the paper cup turret. The demolding assembly has a cup-dispensing cavity, a cup-dispensing notch communicating with the cup-dispensing cavity for allowing the paper cup to enter the cup-dispensing cavity, and a negative pressure hole for adsorbing the paper cup. Along the rotation direction of the paper cup turret, the cup-dispensing notch is located on the upstream side of the cup-dispensing cavity, and the negative pressure hole is located on the downstream side of the cup-dispensing cavity.

[0006] In one embodiment of this application, the demolding assembly includes a sliding member slidably disposed between the flipping assembly and the paper cup turret along the radial direction of the paper cup turret, and a demolding member disposed on the sliding member; the demolding member has an arc surface that surrounds the cup cavity and cooperates with the mold, and a negative pressure hole is opened on the arc surface.

[0007] In one embodiment of this application, the central angle corresponding to the arc surface is less than or equal to 180°.

[0008] In one embodiment of this application, the central angle corresponding to the arc surface is less than or equal to 90°, and the upper edge of the arc surface is flush with or lower than the center position of the arc surface.

[0009] In one embodiment of this application, the demolding assembly further includes a plurality of claw hooks arranged sequentially along the circumferential direction of the arc surface on the demolding member. The claw hooks are located on the side of the arc surface near the paper cup turret and at least partially protrude from the arc surface. The mold is provided with a plurality of hook grooves that cooperate with the claw hooks along the sliding direction of the demolding member. The claw hooks can slide in the hook grooves, and the hook grooves and claw hooks correspond one to one.

[0010] In one embodiment of this application, the demolding assembly further includes a guide rail, an adjusting rod, and a crank. The guide rail is fixed to the frame radially along the paper cup turret. The sliding member is provided with a guide groove that matches the guide rail. The guide groove is slidably embedded in the guide rail. The crank is rotatably disposed on the side of the frame away from the sliding member and the paper cup turret. The two ends of the adjusting rod are rotatably connected to the crank and the sliding member, respectively.

[0011] In one embodiment of this application, a cup dispensing assembly is also included. The cup dispensing assembly includes a lifting rod that is vertically mounted on the frame and a top cup extending from the top of the lifting rod toward the direction of the flipping assembly. The receiving member has a through notch that matches the top cup along the opening direction of the receiving hole, and the through notch communicates with the receiving hole. When the receiving member is flipped to a preset angle, the end of the top cup away from the lifting rod can be raised to enter the receiving hole and the through notch to push out the paper cup, and at least part of the top cup is exposed in the receiving member.

[0012] In one embodiment of this application, the flipping assembly further includes a movable arm and a limiting member. A receiving member is fixed to one end of the movable arm, and the other end of the movable arm is rotatably disposed on a fixed member. The limiting member is disposed at one end of the movable arm near the receiving member. The fixed member is provided with a groove that matches the limiting member along the rotation direction of the movable arm relative to the fixed member. One end of the limiting member is embedded in the groove and can slide within the groove.

[0013] In one embodiment of this application, the limiting member includes a limiting shaft movably inserted into the movable arm, and a limiting part and a sliding part respectively provided at both ends of the limiting shaft. The movable arm is provided with a limiting groove that matches the limiting part. The limiting part is embedded in the limiting groove and can slide within the limiting groove. The sliding part is embedded in the sliding groove and can slide within the sliding groove.

[0014] In one embodiment of this application, the flipping assembly further includes a first linkage mechanism and a first cam. One end of the first linkage mechanism is rotatably disposed on the fixed member and fixedly connected to the end of the movable arm away from the receiving member. The first cam is driven and connected to the other end of the first linkage mechanism so as to drive the movable arm to rotate relative to the fixed member through the first linkage mechanism.

[0015] In summary, when the demolding component slides close to the paper cup turret, the paper cup on the mold can enter the cup-ejection cavity through the cup-ejection notch, allowing the negative pressure hole to attract the paper cup on the mold. When the demolding component slides away from the paper cup turret and approaches the tilting component, it can demold the attracted paper cup from the mold through the negative pressure hole and transfer it to the receiving hole of the receiving component. This allows the paper cup to be demolded and transferred to the tilting station. The cup-ejection notch allows the demolding component to slide directly close to the paper cup turret again after completing one demolding of the paper cup. This ensures that the next mold carrying a paper cup on the paper cup turret can directly enter the cup-ejection cavity through the cup-ejection notch, be attracted by the negative pressure hole, and be demolded. This avoids the demolding component having to be inserted into the mold from the opening of the cup-ejection cavity, thus saving the waiting time for the mold to rotate into place and improving the demolding efficiency of the paper cup.

[0016] Furthermore, the design of the movable arm increases the distance the paper cups travel during flipping, facilitating flexible arrangement of subsequent processing mechanisms. The movable arm, in conjunction with limiting components and sliding grooves, ensures stability during long-distance flipping, thereby expanding the overall applicability of the cup-flipping mechanism. The design of the top cup component extending towards the receiving component, along with the through-hole on the receiving component, ensures the lifting rod remains outside the receiving component. This allows the receiving component to directly reset and flip the next paper cup after the top cup component has completely pushed the paper cup out of the receiving hole, avoiding the need to wait for the lifting rod to descend and disengage from the receiving hole. This prevents interference between the receiving component and the lifting rod, saves time during the cup flipping process, and improves the efficiency of cup flipping and transport.

[0031] Considering that the existing technologies for demolding and flipping paper cups are not well-designed, the demolding and flipping of paper cups are unstable, the coordination with the multi-station paper cup turret is not good, and the short distance after demolding and flipping is not conducive to the flexible layout of other mechanisms, this application provides a cup-dispensing and flipping mechanism. This mechanism can improve the efficiency of the demolding component in demolding paper cups on the multi-station paper cup turret, increase the distance of paper cup transmission and flipping, and ensure that the paper cups are smoothly and accurately transmitted to the next station.

[0032] For details, please refer to Figures 1 to 5As shown, a cup-dispensing and flipping mechanism for conveying and flipping paper cups 100 includes a frame 10, a paper cup turret 20, a flipping assembly 30, and a demolding assembly 40. The paper cup turret 20 is rotatably mounted on the frame 10 and has a plurality of molds 21 for accommodating the paper cups 100 along its circumference. The flipping assembly 30 includes a receiving member 31 and a fixing member 32 mounted on the frame 10. The receiving member 31 is rotatably mounted on the fixing member 32 and has a receiving hole 200 for accommodating the paper cups 100. The demolding assembly 40 is slidably disposed between the flipping assembly 30 and the paper cup turret 20 along the radial direction of the paper cup turret 20. The demolding assembly 40 has a cup discharge cavity 300, a cup discharge notch 301 communicating with the cup discharge cavity 300 and used to allow the paper cup 100 to enter the cup discharge cavity 300, and a negative pressure hole 400 for adsorbing the paper cup 100. Along the rotation direction of the paper cup turret 20, the cup discharge notch 301 is located on the upstream side of the cup discharge cavity 300, and the negative pressure hole 400 is located on the downstream side of the cup discharge cavity 300.

[0033] For more details, please refer to Figure 1 and Figure 2 As shown, when the demolding assembly 40 slides close to the paper cup turret 20, the paper cup 100 on the mold 21 can enter the cup outlet cavity 300 through the cup outlet notch 301, so that the negative pressure hole 400 can adsorb the paper cup 100 on the mold 21. When the demolding assembly 40 slides away from the paper cup turret 20 and closes to the flipping assembly 30, the demolding assembly 40 can demold the adsorbed paper cup 100 from the mold 21 through the negative pressure hole 400 and transfer it to the receiving hole 200 of the receiving member 31, so that the paper cup 100 can be demolded and transferred to the flipping assembly 30. The cup ejection notch 301 allows the demolding component 40 to slide directly back to the cup turret 20 after demolding the paper cup 100 once. This ensures that the next mold 21 carrying the paper cup 100 can directly enter the cup ejection cavity 300 through the cup ejection notch 301, be attracted by the negative pressure hole 400, and be demolded. This avoids the demolding component 40 having to be inserted into the mold 21 only through the opening of the cup ejection cavity 300, thus saving the waiting time for the mold 21 to rotate into place and improving the demolding efficiency of the paper cup 100.

[0034] It is worth mentioning that in this embodiment, the cup ejection cavity 300 and cup ejection notch 301 of the demolding component 40 and the mold 21 in the paper cup turret 20 are on the same horizontal plane. The cup ejection notch 301 is located on the upstream side of the cup ejection cavity 300, and the negative pressure hole 400 is located on the downstream side of the cup ejection cavity 300. This allows the demolding component 40 to slide close to the paper cup turret 20 in advance before the mold 21 has rotated into place. The mold 21 can enter the cup ejection cavity 300 through the cup ejection notch 301 without structural interference with the demolding component 40. This saves the waiting time for the demolding component 40 to wait for the mold 21 to rotate into place, thereby improving the demolding efficiency of the paper cup 100.

[0035] In this embodiment, the demolding assembly 40 includes a sliding member 41 slidably disposed between the flipping assembly 30 and the paper cup turret 20 along the radial direction of the paper cup turret 20, and a demolding member 42 disposed on the sliding member 41; the demolding member 42 has an arc surface 421 that forms the cup cavity 300 and cooperates with the mold 21, and a negative pressure hole 400 is opened on the arc surface 421.

[0036] For details, please refer to Figure 1 and Figure 2 As shown, the sliding member 41 is disposed between the flipping component 30 and the paper cup turret 20, so that the demolding member 42 can slide repeatedly between the flipping component 30 and the paper cup turret 20. The arc surface 421 can form the cup outlet cavity 300 and cooperate with the mold 21, so that when the demolding member 42 slides close to the paper cup turret 20, the mold 21 can directly enter the cup outlet cavity 300 through the cup outlet notch 301. The negative pressure hole 400 is opened on the arc surface 421, so that when the arc surface 421 abuts against the mold 21, the paper cup 100 on the mold 21 can be attracted to the paper cup 100 by the negative pressure hole 400, thereby realizing the demolding of the paper cup 100 when the demolding member 42 slides, ensuring the smooth demolding of the paper cup 100.

[0037] In this embodiment, the central angle corresponding to the arc surface 421 is less than or equal to 180°.

[0038] For details, please refer to Figures 1 to 3 As shown, the central angle corresponding to the arc surface 421 is less than or equal to 180°, which can physically ensure that the demolding component 42 will not structurally interfere with the mold 21 when it slides close to the paper cup turret 20. This allows the mold 21 to directly enter the cup-ejection cavity 300 formed by the arc surface 421 from the cup-ejection notch 301 when it rotates close to the demolding component 42. This enables the demolding component 42 to slide between two adjacent molds 21 before the mold 21 is rotated to its final position, avoiding structural interference between the paper cup 100 on the mold 21 and the demolding component 42 when the demolding component 42 slides between the two adjacent molds 21 in advance. This speeds up the demolding process and improves the demolding efficiency.

[0039] In this embodiment, the central angle corresponding to the arc surface 421 is less than or equal to 90°, and the upper edge of the arc surface 421 is flush with or lower than the center position of the arc surface 421.

[0040] For details, please refer to Figures 1 to 4As shown, the central angle corresponding to the arc surface 421 is less than or equal to 90°, and the upper edge of the arc surface 421 is flush with or lower than the center position of the arc surface 421. This allows the receiving member 31 to directly flip the paper cup 100 after the demolding member 42 transfers the paper cup 100 into the receiving hole 200 of the receiving member 31. This avoids structural interference between the paper cup 100 and the demolding member 42 when the receiving member 31 flips, thereby saving the time that the receiving member 31 waits for the demolding member 42 to slide off, and thus improving the efficiency of the demolding and flipping process of the paper cup 100.

[0041] In this embodiment, the demolding assembly 40 further includes a plurality of claw hooks 43 arranged sequentially along the circumference of the arc surface 421 on the demolding member 42. The claw hooks 43 are located on the side of the arc surface 421 near the paper cup turret 20 and at least partially protrude from the arc surface 421. The mold 21 is provided with a plurality of hook grooves 500 that cooperate with the claw hooks 43 along the sliding direction of the demolding member 42. The claw hooks 43 can slide in the hook grooves 500, and the hook grooves 500 and the claw hooks 43 correspond one to one.

[0042] For details, please refer to Figures 1 to 3 As shown, multiple claw hooks 43 are provided circumferentially along the arc surface 421, and the claw hooks 43 at least partially protrude from the arc surface 421. When the arc surface 421 abuts against the mold 21, the claw hooks 43 can assist in gripping the edge of the paper cup 100. The hook grooves 500 on the mold 21 correspond one-to-one with the claw hooks 43, which can avoid structural interference between the mold 21 and the claw hooks 43, further ensuring that the paper cup 100 can be smoothly demolded from the mold 21, and ensuring the quality of demolding of the paper cup 100.

[0043] In this embodiment, the demolding assembly 40 further includes a guide rail 44, an adjusting rod 45, and a crank 46. The guide rail 44 is fixed to the frame 10 radially along the paper cup turret 20. The sliding member 41 is provided with a guide groove 900 that matches the guide rail 44. The guide groove 900 is slidably embedded in the guide rail 44. The crank 46 is rotatably disposed on the side of the frame 10 away from the sliding member 41 and the paper cup turret 20. The two ends of the adjusting rod 45 are rotatably connected to the crank 46 and the sliding member 41, respectively.

[0044] For details, please refer to Figure 1 and Figure 2 As shown, the sliding member 41 can slide between the flipping component 30 and the paper cup turret 20 through the guide groove 900 and the guide rail 44. The rotation of the crank 46 drives the adjusting rod 45 to drive the sliding member 41 to slide back and forth. On the one hand, it is convenient to accurately control the sliding distance of the sliding member 41, which facilitates the demolding component 42 to accurately demold the paper cup 100. On the other hand, the mechanical timing drive can ensure the stability and reliability of the demolding process, thereby improving the demolding and transmission efficiency and quality of the paper cup 100.

[0045] In this embodiment, a cup dispensing assembly 50 is also included. The cup dispensing assembly 50 includes a lifting rod 51 that is movably mounted on the frame 10, and a top cup member 52 that extends from the top of the lifting rod 51 toward the direction of the flipping assembly 30. The receiving member 31 is provided with a through notch 600 that matches the top cup member 52 along the opening direction of the receiving hole 200. The through notch 600 communicates with the receiving hole 200. When the receiving member 31 is flipped to a preset angle, the end of the top cup member 52 away from the lifting rod 51 can be raised to enter the receiving hole 200 and the through notch 600 to push out the paper cup 100, and at least part of the top cup member 52 is exposed in the receiving member 31.

[0046] For details, please refer to Figures 1 to 6 As shown, the top cup component 52 extends from the top of the lifting rod 51 toward the direction close to the flipping assembly 30, and the receiving component 31 is provided with a corresponding through notch 600, so that when the receiving component 31 drives the paper cup 100 to complete the flipping, the top cup component 52 can enter the receiving hole 200 to push the paper cup 100 out to the next station. Furthermore, since at least part of the top cup component 52 is exposed in the receiving component 31, when the top cup component 52 pushes the paper cup 100 out through the through notch 600, the receiving component 31 can directly flip and reset to carry out the next flipping process of the paper cup 100, avoiding structural interference between the receiving component 31 and the lifting rod 51 when the receiving component 31 flips directly, thereby speeding up the flipping process of the paper cup 100 and thus improving the overall production efficiency of the paper cup 100.

[0047] In this embodiment, the flipping assembly 30 further includes a movable arm 33 and a limiting member 34. The receiving member 31 is fixed to one end of the movable arm 33, and the other end of the movable arm 33 is rotatably disposed on the fixing member 32. The limiting member 34 is disposed at the end of the movable arm 33 near the receiving member 31. The fixing member 32 is provided with a groove 700 that cooperates with the limiting member 34 along the rotation direction of the movable arm 33 relative to the fixing member 32. One end of the limiting member 34 is embedded in the groove 700 and can slide within the groove 700.

[0048] For details, please refer to Figures 1 to 5 As shown, the movable arm 33 increases the distance the paper cup 100 can rotate, allowing for a more flexible layout of the mechanism that processes the paper cup 100 in the next step. This avoids structural interference between the mechanism that processes the paper cup 100 in the next step, such as a multi-station paper cup 100 processing turret, and the cup dispensing and rotating mechanism, thus improving the overall applicability of the cup dispensing and rotating mechanism. The cooperation between the limiting component 34 and the slide 700 ensures the stability of the movable arm 33 during long-distance rotation, enabling the paper cup 100 in the accommodating component 31 to be accurately transferred to the next station, thereby improving the quality of the paper cup 100 during production and transportation.

[0049] In this embodiment, the limiting member 34 includes a limiting shaft 341 movably inserted into the movable arm 33, and a limiting part 342 and a sliding part 343 located at both ends of the limiting shaft 341. The movable arm 33 is provided with a limiting groove 800 that cooperates with the limiting part 342. The limiting part 342 is embedded in the limiting groove 800 and can slide within the limiting groove 800. The sliding part 343 is embedded in the sliding groove 700 and can slide within the sliding groove 700.

[0050] For details, please refer to Figure 4 and Figure 5 As shown, the sliding part 343, in conjunction with the limiting shaft 341, allows the movable arm 33 to slide within the slide groove 700, achieving stable rotation of the movable arm 33 and the accommodating member 31. The limiting part 342 can slide within the limiting groove 800 of the movable arm 33, thereby avoiding possible structural jamming between the sliding part 343 and the fixing member 32 due to errors when the sliding part 343 is installed and embedded in the slide groove 700. This further ensures that the movable part can drive the movable arm 33 to slide smoothly within the slide groove 700, thereby ensuring the quality and efficiency of the paper cup 100 flipping in the accommodating member 31.

[0051] In this embodiment, the flipping assembly 30 further includes a first linkage mechanism 35 and a first cam 36. One end of the first linkage mechanism 35 is rotatably disposed on the fixing member 32 and fixedly connected to the end of the movable arm 33 away from the receiving member 31. The first cam 36 is driven to the other end of the first linkage mechanism 35 so as to drive the movable arm 33 to rotate relative to the fixing member 32 through the first linkage mechanism 35.

[0052] For details, please refer to Figure 1 and Figure 2 As shown, the movable arm 33 completes the flipping process of the paper cup 100 through the first linkage mechanism 35 and the first cam 36, which facilitates precise control of the reciprocating flipping angle of the paper cup 100, ensures the stability and reliability of the reciprocating flipping, and thus improves the overall quality of the paper cup 100 transmission and flipping process.

[0053] It is worth mentioning that in this embodiment, the lifting rod 51 in the cup dispensing assembly 50 also realizes the reciprocating motion of the cup top component 52 through a cam structure and a linkage mechanism. Similarly, in other embodiments, the transmission, flipping and ejection process of the paper cup 100 can also be driven by other methods such as an electronic servo motor, as long as the stability and accessibility of the transmission, flipping and ejection process of the paper cup 100 can be ensured. There are no restrictions here, and the specific arrangement will not be described in detail. The specific arrangement can be referred to the arrangement of the first cam 36 and the first linkage mechanism 35 mentioned above.

[0054] 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 described. 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.

[0055] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
