A bottle unscrambler and method for an automatic packaging apparatus

Abstract

This invention discloses a bottle unscrambler and method for an automatic packaging equipment, relating to the technical field of bottle unscrambler technology. The bottle unscrambler and method for this automatic packaging equipment includes a frame and a turntable. The turntable is divided into a waiting area, a feeding area, and a turning area. Multiple fins are evenly arranged circumferentially on the turntable. The invention incorporates fins, pinions, and teeth. When passing through the waiting area, the pinion engages sequentially with multiple segments of teeth on a cam ring, causing the fins to deflect in one direction around the cam shaft, reducing the gap between adjacent fins and thus expanding the overall space of the feeding area. When the turntable continues to rotate to the feeding area, the pinion engages sequentially with multiple segments of teeth on another cam ring, causing the fins to deflect in the opposite direction to the waiting area, increasing the gap between adjacent fins and expanding the bottle's entry space in the feeding area, thereby increasing the probability of the bottle entering the slot.

Description

Technical Field

[0001] This invention relates to the field of bottle unscrambler technology, specifically to a bottle unscrambler and bottle unscrambler method for automatic packaging equipment. Background Technology

[0002] The rotary automatic bottle unscrambler is an automated device that uses a combination of centrifugal force and mechanical straightening to automatically sort, orient, correct the posture of disordered bottles, and output them in an orderly manner. Its core working principle is as follows: after entering the rotating bottle unscrambler, the disordered bottles move towards the edge of the disc under centrifugal force. Combined with the outer bottle-turning baffles and bottle-supporting ramps, bottles that are tilted, reversed, or have abnormal postures are turned over and straightened, ultimately resulting in a continuous and stable output of bottles in a uniform upright posture. This provides orderly bottle feeding conditions for subsequent filling, capping, and labeling processes.

[0003] To ensure the slots effectively constrain the bottles, limiting lateral movement and facilitating subsequent flipping and bottle ejection, the slots should be slightly larger than the bottle diameter. However, in actual use, especially with large bottles, when the bottles are fed from above, the uncontrollable direction of descent, coupled with the limited slot size, causes the bottles to easily become stuck on the fins and fail to be inserted into their designated positions in time. This results in multiple slots being left empty and wasted, requiring repeated adjustments to the speed of the matching conveyor belt, making it difficult to meet the continuous high-speed bottle feeding requirements of automated production lines. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a bottle unscrambler and bottle unscrambler method for automatic packaging equipment, solving the problem of difficulty in getting the bottles into the slots.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bottle unscrambler for automatic packaging equipment, comprising a frame, and further comprising: The turntable is divided into a waiting area, a feeding area, and a flipping area. Multiple fins are evenly arranged along the circumference of the turntable, and grooves are formed between adjacent fins. The rotation of the turntable drives the fins to pass through the waiting area, the feeding area, and the flipping area in sequence, guiding the bottles to flip and arrange in an orderly manner. An adjustment assembly, fixed to the frame, includes a small gear mounted on a fin; The convex rings are provided in two sets, both concentric with the turntable. The pinion is located between the two sets of convex rings. The two sets of convex rings have segmented teeth on the parts located in the waiting area or the feeding area. When the turntable rotates, the teeth and the pinion cooperate to deflect the fins. The slot becomes smaller in the waiting area and larger in the feeding area, increasing the probability of the bottle entering the slot in the feeding area.

[0006] Furthermore, the turntable is a first turntable and a second turntable, and the upper and lower ends of the fin are fixed with a first convex shaft. The fin is rotatably mounted between the first turntable and the second turntable through the first convex shaft. The first turntable and the second turntable rotate synchronously. The adjustment assembly also includes a first fixing member, which is fixedly connected to the frame. The convex ring is a first convex ring and a second convex ring, which are disposed on the upper surface of the first fixing member. The tooth segment is disposed on the side of the second convex ring located in the waiting area near the pinion, which can cooperate to drive the fins to deflect circumferentially on the first and second turntables, reducing the distance between the fins in the waiting area. The tooth segment is disposed on the side of the first convex ring located in the feeding area near the pinion, which can cooperate to drive the distance between the fins in the feeding area to increase.

[0007] Furthermore, the first fixing member is a double cylindrical structure with an upper and lower cylinder. The upper surface of the upper cylinder of the first fixing member is in clearance fit with the lower surface of the second turntable, and the diameter of the upper cylinder of the first fixing member is the same as the diameter of the first turntable.

[0008] Furthermore, it also includes a limiting component, which includes: A first positioning plate, which corresponds to the position of a first convex shaft, presses against the first convex shaft to constrain its deflection; The slider is located on the upper surface of the first positioning plate, and the second turntable has a groove that cooperates with the slider, so that the first positioning plate can rotate synchronously with the turntable, and the first positioning plate has a degree of freedom in the radial direction of the second turntable. The slide rail is formed on the upper surface of the first fixing member. The lower surface of the first positioning plate away from the first convex shaft is provided with a first fixing shaft. The first fixing shaft can slide along the slide rail. The slide rail has an arc-shaped structure, and the distance between the position of the slide rail near the teeth and the central axis of the first fixing member is increased.

[0009] Furthermore, the turntable is a third turntable, and a second convex shaft is fixedly provided on the side of the fin plate near the third turntable. The fin plate is rotatably mounted on the outer surface of the third turntable through the second convex shaft. The adjustment assembly also includes a second fixing member, which is fixedly connected to the frame. The second fixing member is a cylindrical structure. The convex rings are a third convex ring and a fourth convex ring, which are located on the outer arc surface of the second fixing member. The tooth segments are located on the side of the third convex ring in the waiting area near the pinion, which can cooperate with the drive fin to deflect radially along the third turntable. The inclination angle of the fin in the waiting area increases sequentially, and the opening on the slot decreases. The tooth segments are located on the side of the fourth convex ring in the feeding area near the pinion, which can cooperate with the drive fin in the feeding area to decrease sequentially, and the opening on the slot increases.

[0010] Furthermore, it also includes a limiting component, which includes: The second positioning plate corresponds to the position of the second convex shaft, and the second positioning plate presses against the second convex shaft to constrain its deflection. The telescopic frame is located on both sides of the second positioning plate, and both ends of the telescopic frame extend into the interior of the third turntable and are slidably connected thereto, so that the second positioning plate can rotate synchronously with the turntable, and the second positioning plate has a degree of freedom in the radial direction of the third turntable. The slide rail is located on the lower surface of the third convex ring and the upper surface of the fourth convex ring. The upper and lower ends of the second positioning plate are provided with second fixed shafts. The second fixed shafts can slide along the slide rail. The slide rail has an arc-shaped structure, and the distance between the slide rail near the teeth and the central axis of the second fixed shaft is reduced.

[0011] Furthermore, it also includes: A spiral plate, the spiral plate being located in the flipping zone; Bottle outlet guide rail, located at the end of the spiral plate, is used for the smooth discharge of the bottle.

[0012] Furthermore, it also includes: A protective ring, located outside the fins, is used to guide the bottle to rotate along the edge of the turntable; The bottle-turning baffle and bottle-supporting ramp are fixed on the frame and are used to enable the inverted bottle to be turned 180°.

[0013] Furthermore, a conveyor is also provided on the frame, and the turntable is located at the end of the conveyor.

[0014] On the other hand, the present invention also provides a bottle unloading method for an automatic packaging device, comprising the following steps: Step 1: After the raw material packaging is unpacked and sterilized by ultraviolet light through the pass-through window, it enters the clean area and the bottle body is sent into the bottle unscrambler. Step 2: The bottle is fed into the feeding area in the bottle unscrambler. At the same time, the turntable rotates. The rotation of the turntable drives the fins to pass through the waiting area and the feeding area in sequence. With the cooperation of the teeth and pinions, the fins deflect, so that the slots can become smaller in the waiting area and larger in the feeding area, making it easier for the bottle to enter the slot. Step 3: Unqualified bottles are automatically removed at the front of the turning zone, the bottles are automatically straightened in the middle of the turning zone, and the material is discharged at the end of the turning zone and conveyed to the lower part of the filling machine via a conveyor belt.

[0015] The present invention has the following beneficial effects: 1. The bottle unscrambler and unscrambler method of this automatic packaging equipment are equipped with fins, pinions, and teeth. When passing through the waiting area, the pinion engages sequentially with multiple teeth on the cam ring, and the fins deflect in one direction around the cam shaft, reducing the gap between adjacent fins and expanding the overall space of the feeding area. When the turntable continues to rotate to the feeding area, the pinion engages sequentially with multiple teeth on another cam ring, and the fins deflect in the opposite direction to the waiting area, increasing the gap between adjacent fins and expanding the space for the bottle to enter the feeding area, thus increasing the probability of the bottle entering the feeding area.

[0016] 2. The bottle unscrambler and unscrambler method of the automatic packaging equipment are equipped with a limiting component. The convex shaft slides along the slide rail, so that the limiting is released in the waiting area and the tooth action area of ​​the feeding area, ensuring that the fin plate can be freely adjusted under the action of the tooth. In the area without tooth action, the limiting is locked to prevent the fin plate from deflecting randomly due to the reaction force or centrifugal force of the bottle collision, thus ensuring the smooth conveying of the bottle.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] The following is based on Figures 1-14 This invention describes the bottle unscrambler and bottle unscrambler method of the automatic packaging equipment provided in embodiments of the present invention.

[0023] On one hand, embodiments of the present invention provide a bottle unscrambler for an automatic packaging device.

[0024] Example 1: Please refer to Figure 1 , Figure 2 and Figure 9The bottle unscrambler of the automatic packaging equipment includes a frame 9, on which a conveyor 1 is also installed. A bottle inlet hopper is located above the conveyor 1. A turntable is located at the end of the conveyor 1. The turntable is divided into a waiting area 14, a feeding area 15, and a turning area 16. Multiple fins 31 are evenly arranged along the circumference of the turntable. A groove is formed between adjacent fins 31. The groove plays a circumferential limiting role for the bottle entering the turntable, preventing the bottle from tipping over or shifting during the movement of the turntable. The rotation of the turntable drives the fins 31 to pass through the waiting area 14, the feeding area 15, and the turning area 16 in sequence, guiding the bottles to be turned and arranged in an orderly manner.

[0025] Specifically, after unpacking the raw material packaging materials, they are sterilized by ultraviolet lamps through a pass-through window and then enter the clean area. The bottles are then placed into the inlet hopper, and conveyor 1 smoothly transports the bottles to the rotary feeding area 15. (e.g.) Figure 9 The rotation of the turntable drives multiple circumferentially evenly arranged fins 31 to perform synchronous circular motion, causing the fins 31 and the slots formed between them to circulate sequentially through the waiting area 14, the feeding area 15, and the flipping area 16. When the slot rotates with the turntable to the feeding area 15, it receives the bottle conveyed by the conveyor 1, achieving initial docking between the bottle and the slot. The turntable continues to rotate, driving the slot containing the bottle into the front section of the flipping area 16. Under the influence of its own weight, the centrifugal force generated by the rotation of the turntable, and the limiting effect of the fins 31, the bottle further adjusts its posture and smoothly inserts into the slots formed by adjacent fins 31, preventing the bottle from tilting or falling off. This ensures that each slot stably accommodates a single bottle, reducing slot waste. The bottle flipping and discharging work is completed sequentially in the middle and end sections of the flipping area 16.

[0026] Please refer to Figures 2-9 To facilitate the entry of the bottle into the slot, an adjustment assembly is also provided. This assembly is fixed to the frame 9 and includes a pinion 41 and two convex rings mounted on the fin plate 31. Two sets of convex rings are provided, both concentric with the turntable. The pinion 41 is located between the two sets of convex rings. The two sets of convex rings have segmented teeth (e.g., teeth on the portion located in the waiting area 14 or the feeding area 15) on the portion of the convex rings. Figure 8 When the turntable rotates, the teeth and pinion 41 work together to deflect the fin plate 31. The slot becomes smaller in the waiting area 14 and larger in the feeding area 15, increasing the probability that the bottle will enter the slot in the feeding area 15.

[0027] Specifically, the slot located in the waiting area 14 does not participate in the bottle handling work. When the slot rotates with the turntable to the waiting area 14, the size of the slot becomes smaller, which can increase the space of the feeding area 15. At this time, the fin plate 31 of the feeding area 15 deflects, making the size of the slot larger, expanding the bottle's accommodating space, so that the bottles conveyed to the feeding area 15 can adjust their posture more smoothly and be inserted into the slot, increasing the probability of the bottle entering the slot in the feeding area 15.

[0028] It should be noted that the enlarged slot cannot accommodate two or more bottles.

[0029] Please refer to Figures 3-9 The turntables are a first turntable 611 and a second turntable 612. The first turntable 611 and the second turntable 612 rotate synchronously. The upper and lower ends of the fin plate 31 are fixed with a first convex shaft 32. The fin plate 31 is rotatably installed between the first turntable 611 and the second turntable 612 through the first convex shaft 32, so that the fin plate 31 can deflect around the first convex shaft 32 in the circumference of the first turntable 611 and the second turntable 612, thereby adjusting the slot spacing formed between adjacent fin plates 31.

[0030] The adjustment assembly also includes a first fixing member 44, which is fixedly connected to the frame 9. The convex rings are a first convex ring 42 and a second convex ring 43, which are located on the upper surface of the first fixing member 44. The teeth are segmented and located on the side of the second convex ring 43 near the pinion 41 in the waiting area 14, indicating that the fins 31 are circumferentially deflected on the first turntable 611 and the second turntable 612, and the spacing between the fins 31 in the waiting area 14 is reduced. The teeth are segmented and located on the side of the first convex ring 42 near the pinion 41 in the feeding area 15, indicating that the spacing between the fins 31 in the feeding area 15 is increased.

[0031] Specifically, the first turntable 611 and the second turntable 612 rotate synchronously, causing the fin plate 31 to perform synchronous circular motion. This causes the fin plate 31 and the groove formed between it to sequentially circulate through the waiting area 14, the feeding area 15, and the flipping area 16. The first fixing member 44 fixes the positions of the first convex ring 42 and the second convex ring 43. (e.g.) Figure 9 When the turntable passes through the waiting area 14, the pinion 41 engages with the multiple teeth on the second convex ring 43 in sequence, and the fin 31 deflects counterclockwise around the first convex shaft 32 in stages, reducing the gap between adjacent fins 31 and expanding the overall space of the feeding area 15. When the turntable continues to rotate to the feeding area 15, the pinion 41 engages with the multiple teeth on the first convex ring 42 in sequence, and the fin 31 deflects clockwise around the first convex shaft 32 in stages, increasing the gap between adjacent fins 31 and expanding the space for the bottle to enter the feeding area 15, thus increasing the probability of the bottle entering the feeding area.

[0032] In addition, at the front of the flipping zone 16, the fins 31 return to their normal spacing, and a single slot can accommodate a single bottle, so that the bottle's posture can be adjusted at the front, enabling the bottle flipping and discharging work to be completed in a stable posture in the middle and end of the flipping zone 16.

[0033] Preferably, the first fixing member 44 is a double cylindrical structure. The upper surface of the cylinder wall of the first fixing member 44 is in clearance fit with the lower surface of the second turntable 612. The upper cylinder reduces external interference to the operation of the pinion 41 and its teeth. The diameter of the upper cylinder of the first fixing member 44 is the same as the diameter of the first turntable 611 and the second turntable 612. The upper cylinder of the first fixing member 44, the first turntable 611 and the second turntable 612 form a radial limit for the bottle. The equal diameter setting prevents the bottle from tipping over during the movement of the first turntable 611 and the second turntable 612.

[0034] Please refer to Figure 10 To facilitate the rotation of the turntable, a drive mechanism 8 is also provided. The drive mechanism 8 includes a rotating shaft 81. The upper end of the rotating shaft 81 passes through the first fixing member 44 and is fixedly connected to the first turntable 611 and the second turntable 612. The lower part of the rotating shaft 81 is rotatably mounted on the frame 9. The lower end of the rotating shaft 81 is sleeved with a first gear 82. The first gear 82 is externally meshed with a second gear 83. A motor 84 is provided on the frame 9. The power output end of the motor 84 is fixedly connected to the central shaft of the second gear 83.

[0035] In addition, the first convex shaft 32 has damping, which can maintain the angle of the fin plate 31 in the area without external force interference. However, in actual operation, the fin plate 31 must rotate synchronously with the turntable to drive the bottle to move along the circumference, and it must also deflect with the first convex shaft 32 to adjust the slot spacing. During this process, collision friction will occur between the fin plate 31 and the bottle. The reaction force generated by the collision will interfere with the normal deflection of the fin plate 31. In the toothless area, the deflection state of the fin plate 31 is only constrained by the damping of the first convex shaft 32 itself. The constraint capacity is limited and it cannot stably maintain the required deflection angle, affecting the stable positioning and smooth conveying of the bottle.

[0036] Therefore, please refer to Figure 4 , Figure 5 and Figure 7 It also includes a limiting component, which includes a first positioning plate 51, a slider 53, and a slide rail 13. The first positioning plate 51 corresponds to the position of the first convex shaft 32 (e.g., Figure 7 The first positioning plate 51 presses against the first convex shaft 32 to constrain its deflection; the slider 53 is provided on the upper surface of the first positioning plate 51, and the second turntable 612 is provided with a sliding groove 54 that cooperates with the slider 53, so that the first positioning plate 51 can rotate synchronously with the turntable, and the first positioning plate 51 has a degree of freedom in the radial direction of the second turntable 612; the slide rail 13 is provided on the upper surface of the first fixing member 44, and the lower surface of the end of the first positioning plate 51 away from the first convex shaft 32 is provided with a first fixing shaft 52, which can slide along the slide rail 13. The slide rail 13 has an arc-shaped structure, and the distance between the position of the slide rail 13 near the teeth and the central axis of the first fixing member 44 is increased.

[0037] Specifically, the rotation of the first turntable 611 and the second turntable 612 drives the slider 53 to move, which in turn drives the entire limiting assembly to move synchronously with the turntable, so that the first fixed shaft 52 slides in the arc track of the slide rail 13 with a fixed radius. At this time, the arc track of the slide rail 13 restricts the radial displacement of the first fixed shaft 52, so that the first positioning plate 51 and the fin plate 31 rotate synchronously, and one end of the first positioning plate 51 directly contacts and locks the first convex shaft 32, so that the fin plate 31 stably maintains the preset deflection angle. In the waiting area 14 and the feeding area 15, to prevent the limiting effect of the first positioning plate 51 from affecting the deflection of the fin plate 31, the distance between the position of the slide rail 13 near the teeth and the central axis of the first fixing member 44 is increased. When the first fixing shaft 52 rotates to this area, the radius of the slide rail 13 increases, causing the first fixing shaft 52 and the first positioning plate 51 connected to it to move radially outward along the second turntable 612. The first positioning plate 51 moves away from the first convex shaft 32 and no longer forms a constraint. At this time, the fin plate 31 is released from the limiting position and can deflect freely under the meshing action of the teeth of the adjusting component and the pinion 41. After the deflection is completed, the slide rail 13 returns to its original position, causing the first positioning plate 51 to approach the first convex shaft 32 again and form a constraint on it. That is, the limiting position is released in the tooth action area of ​​the waiting area 14 and the feeding area 15, ensuring that the fin plate 31 can be freely adjusted under the action of the teeth; in the toothless action area, the limiting position is locked to prevent the fin plate 31 from deflecting randomly due to the reaction force or centrifugal force of the bottle collision, ensuring the smooth conveying of the bottle.

[0038] Please refer to Figure 2 and Figure 9 In order to automatically remove unqualified bottles before turning them over, a bottle-pushing impeller 11 is also set up to sweep bottles that have not entered the slot, are tilted, or are stacked back to the feeding area 15.

[0039] To flip the inverted bottles, a protective ring 10, a bottle-flipping baffle 71, and a bottle-supporting ramp 72 are also provided. The protective ring 10 is located outside the turntable and is used to guide the bottle to rotate along the edge of the turntable. The bottle-flipping baffle 71 and the bottle-supporting ramp 72 are fixed on the frame 9. When the slot containing the bottle enters the flipping area 16 with the turntable, the inverted bottle in the slot is flipped by the cooperation of the bottle-flipping baffle 71 and the bottle-supporting ramp 72 with the difference in diameter between the bottle mouth and the bottle bottom. The inverted bottle is flipped to a uniform posture with the bottle mouth facing upward. The upright bottle passes smoothly through the flipping area 16 and maintains its original posture.

[0040] To facilitate the discharge of the bottles, a spiral plate 12 and a bottle discharge guide rail 2 are also provided. The spiral plate 12 is located in the flipping zone 16, and the bottle discharge guide rail 2 is located at the end of the spiral plate 12. This is used to smoothly discharge the bottles and move them downstream in an orderly and uniform manner.

[0041] In use, the raw material packaging is first unpacked and sterilized by ultraviolet light through the transfer window before entering the clean area. The bottle body is then sent into the bottle unscrambler, and the conveyor 1 smoothly transports the bottle body to the turntable feeding area 15.

[0042] Secondly, the synchronous rotation of the first turntable 611 and the second turntable 612 drives the fin plate 31 to pass through the waiting area 14 and the feeding area 15 in sequence. When passing through the waiting area 14, the pinion 41 meshes with the multiple teeth on the second cam ring 43 in sequence, and the fin plate 31 deflects counterclockwise around the first cam shaft 32 in stages (e.g., Figure 9 (As indicated by the arrow), the gap between the slots of adjacent fins 31 is reduced to expand the overall space of the feeding area 15. When the turntable continues to rotate to the feeding area 15, the pinion 41 meshes sequentially with the multiple teeth on the first convex ring 42, and the fins 31 deflect clockwise around the first convex shaft 32 in stages (as shown by the arrow). Figure 9 (As indicated by the arrow), this increases the spacing between adjacent fins 31, expanding the space for the bottle to enter the feeding area 15 and increasing the probability of the bottle entering the feeding area. During the above process, the first positioning plate 51 is released from its limit in the waiting area 14 and the toothed area of ​​the feeding area 15, ensuring that the fins 31 can be freely adjusted under the action of the teeth; in the area without toothed action, it is locked to prevent the fins 31 from deflecting randomly due to the reaction force of the bottle collision or centrifugal force, ensuring the smooth transport of the bottle.

[0043] Finally, the first turntable 611 and the second turntable 612 rotate into the flipping zone 16. In the front section of the flipping zone 16, the fins 31 return to their normal spacing and adjust the posture of the bottle so that the bottle-dispensing impeller 11 can automatically remove unqualified bottles and sweep them back to the feeding zone 15. In the middle section of the flipping zone 16, the bottle-flipping baffle 71 and the bottle-supporting ramp 72 flip the inverted bottle into a uniform posture with the bottle mouth facing upward. In the end section of the flipping zone 16, the spiral plate 12 and the bottle-discharging guide rail 2 complete the discharge and convey the material to the lower part of the filling machine via the conveyor belt.

[0044] Example 2: Please refer to Figures 11-17 The difference between this embodiment and embodiment one is the different way the fin plate 31 deflects. Here, the turntable is the third turntable 62. The fin plate 31 is fixed with a second convex shaft 33 on the side near the third turntable 62. The fin plate 31 is rotatably mounted on the outer surface of the third turntable 62 through the second convex shaft 33, so that the fin plate 31 can deflect around the second convex shaft 33 in the radial direction of the third turntable 62, thereby adjusting the deflection angle of adjacent fin plates 31.

[0045] The adjustment assembly also includes a second fixing member 47, which is fixedly connected to the frame 9. The second fixing member 47 is a cylindrical structure with a third convex ring 45 and a fourth convex ring 46. The third convex ring 45 and the fourth convex ring 46 are located on the outer arc surface of the second fixing member 47. The teeth are segmented and located on the side of the third convex ring 45 in the waiting area 14 near the pinion 41, indicating that the fin 31 is radially deflected along the third turntable 62. The tilt angle of the fin 31 in the waiting area 14 increases sequentially, and the opening on the slot decreases. The teeth are segmented and located on the side of the fourth convex ring 46 in the feeding area 15 near the pinion 41, indicating that the tilt angle of the fin 31 in the feeding area 15 decreases sequentially, and the opening on the slot increases.

[0046] Specifically, the rotation of the third turntable 62 drives the fin plate 31 to perform a synchronous circular motion, causing the fin plate 31 and the grooves formed therein to sequentially circulate through the waiting area 14, the feeding area 15, and the flipping area 16. The second fixing member 47 fixes the positions of the third convex ring 45 and the fourth convex ring 46. (e.g.) Figure 17 When passing through waiting area 14, the pinion 41 engages sequentially with the multiple teeth on the third cam ring 45, and the fin 31 deflects clockwise around the second cam shaft 33 in stages (as shown). Figure 17 (As indicated by the arrow), the opening on the slot between adjacent fins 31 is reduced, so that when the fin 31 enters the feeding zone 15, the deflection angle reaches its maximum. The turntable continues to rotate, and the pinion 41 meshes sequentially with the multiple teeth on the fourth convex ring 46. The fin 31 deflects counterclockwise around the second convex shaft 33 in stages (as shown by the arrow). Figure 17 As the inclination angle of the fin 31 decreases, the opening of the slot formed between adjacent fins 31 becomes larger, expanding the inlet space of the bottle in the feeding area 15. Furthermore, the inclined fin 31 can guide the bottle's entry, increasing the probability of the bottle entering the slot.

[0047] It should be noted that for automatic bottle unloading of large bottles, the height of the fin plate 31 may be relatively high in order to maintain the stability of the bottle body. If the deflection of the waiting area 14 is abandoned and the fin plate 31 is driven to reach the maximum deflection angle directly in the front section of the feeding area 15, the adjacent fin plate 31 in the waiting area 14 will be in a vertical state, which will block the deflection of the fin plate 31 in the front section of the feeding area 15.

[0048] In addition, the deflection and tilting of the fin plate 31 will cause the lower port of the slot to become smaller, making it difficult for the bottom of the bottle to effectively touch the bottom, which may cause a slight tilt. However, in the front section of the flipping zone 16, the fin plate 31 deflects and returns to a vertical state. The centrifugal force of the rotation of the third turntable 62 and the limiting of the fin plate 31 enable the bottle to be adjusted in the front section of the flipping zone 16, so that the bottle flipping and discharging work can be completed in a stable posture in the middle and end sections of the flipping zone 16.

[0049] Please refer to Figures 12-16To maintain the required deflection angle of the fin plate 31, a limiting assembly is also provided. This limiting assembly includes a second positioning plate 56, a telescopic frame 55, and a slide rail 13. The second positioning plate 56 corresponds to the position of the second convex shaft 33 (e.g., Figure 14 and Figure 15 The second positioning plate 56 presses against the second convex shaft 33 to constrain its deflection; the telescopic frame 55 is provided on both sides of the second positioning plate 56, and the two ends of the telescopic frame 55 extend into the interior of the third turntable 62 and slide to connect with it, so that the second positioning plate 56 can rotate synchronously with the turntable, and the second positioning plate 56 has a degree of freedom in the radial direction of the third turntable 62; the slide rail 13 is opened on the lower surface of the third convex ring 45 and the upper surface of the fourth convex ring 46, and the upper and lower ends of the second positioning plate 56 are provided with second fixed shafts 57, which can slide along the slide rail 13. The slide rail 13 has an arc-shaped structure, and the distance between the position of the slide rail 13 near the teeth and the central axis of the second fixed shaft 57 is reduced.

[0050] Specifically, the rotation of the third turntable 62 drives the telescopic frame 55 to move, causing the second fixed shaft 57 to slide within the arc track of the slide rail 13 with a fixed radius. At this time, the arc track of the slide rail 13 restricts the radial displacement of the second fixed shaft 57. During this process, one end of the second positioning plate 56 directly contacts and locks the end face of the second convex shaft 33, so that the fin plate 31 can stably maintain the preset deflection angle. In the waiting area 14 and the feeding area 15, in order to avoid the limiting effect of the second positioning plate 56 affecting the deflection of the fin plate 31, the distance between the position of the slide rail 13 near the teeth and the central axis of the second fixed shaft 57 is reduced. When the second fixed shaft 57 rotates to this area, the second positioning plate 56 moves away from the second convex shaft 33. At this time, the fin plate 31 is released from the limiting position and can deflect freely under the meshing action of the teeth of the adjusting component and the pinion 41. After the deflection is completed, the slide rail 13 returns to its original position, so that the second positioning plate 56 moves closer to the second convex shaft 33 again and forms a constraint on it. That is, the limit is released in the waiting area 14 and the feeding area 15 where the teeth act, so that the fin plate 31 can be freely adjusted under the action of the teeth; the limit is locked in the area where the teeth do not act, so as to prevent the fin plate 31 from deflecting randomly due to the reaction force of the bottle collision or centrifugal force, and to ensure the smooth transport of the bottle.

[0051] On the other hand, embodiments of the present invention also provide a bottle unloading method for an automatic packaging device, comprising the following steps: Step 1: After the raw material packaging is unpacked and sterilized by ultraviolet light through the pass-through window, it enters the clean area and the bottle body is sent into the bottle unscrambler. Step 2: The bottle body is fed into the feeding area 15 in the bottle unscrambler. At the same time, the turntable rotates. The rotation of the turntable drives the fin plate 31 to pass through the waiting area 14 and the feeding area 15 in sequence. With the cooperation of the teeth and the pinion 41, the fin plate 31 is deflected, so that the slot can become smaller in the waiting area 14 and larger in the feeding area 15, which makes it easier for the bottle body to enter the slot. Step 3: Unqualified bottles are automatically removed at the front of the flipping zone 16, the bottles are automatically straightened in the middle of the flipping zone 16, and the material is discharged at the end of the flipping zone 16 and conveyed to the lower part of the filling machine by the conveyor belt.
