Description

Technical Field

[0001] This application belongs to the technical field of medicine bottle manufacturing, and more specifically, relates to a bottle flipping structure. Background Technology

[0002] Medicine bottles are containers for holding medicines, primarily used for liquid, powdered, or granular medications. During the production and processing of medicine bottles, empty bottles need to be inverted and flipped while being conveyed by a conveyor belt for subsequent operations.

[0003] The existing bottle flipping structure includes a guide flipping channel located between two conveyor belts, with one conveyor belt higher than the other. The top of the guide flipping channel is located at the unloading end of the higher conveyor belt, and the bottom of the guide flipping channel is located at the loading end of the lower conveyor belt. The guide flipping channel is set at an angle so that the bottles inside can automatically flip by gravity.

[0004] However, due to the limited internal space of the guide flipping channel, bottles can easily get stuck in the channel during the falling and flipping process, causing subsequent bottles to get stuck together after entering the channel, thus affecting bottle production efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a bottle flipping structure to solve the technical problem in the prior art where, due to the limited internal space of the guide flipping channel, bottles are easily stuck in the channel during the falling and flipping process, causing subsequent bottles to get stuck together after entering the channel, thus affecting bottle production efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a bottle-flipping structure, comprising: Two mounting plates are respectively installed on both sides of the conveyor belt; Two turntables correspond one-to-one with the two mounting plates, and the turntables are rotatably mounted on the mounting plates; Two movable rods are coaxially corresponding to the two turntables and are slidably connected to the turntables along their own axes, with one end of each movable rod located above the conveyor belt; Two clamps, corresponding one-to-one with the two movable rods, are fixed to the ends of the movable rods located above the conveyor belt; Rotating components, respectively mounted on the two mounting plates, are used to drive the turntable to rotate; and The drive mechanism is respectively mounted on the two mounting plates and is used to drive the moving rod to slide. In one possible implementation, based on the above technical solutions, the mounting plate has an arc-shaped track, with the middle of the arc-shaped track higher than both ends; the bottle-flipping structure further includes: Two movable blocks, corresponding one-to-one with the two arc-shaped tracks, are slidably connected within the arc-shaped tracks in the direction of conveyor belt transport; and Two sets of pushing components are respectively mounted on the two mounting plates, used to drive the moving block to slide within the arc-shaped track; When the moving block slides from one end of the arc-shaped track near the bottle feeding direction to the other end, the rotating component drives the turntable to rotate automatically by 180°.

[0007] In one possible implementation, based on the above technical solutions, the rotating component includes: Rotating gears are coaxially fixed to the outside of the turntable; and An arc-shaped rack is fixed inside the arc-shaped track and is always meshed with the rotating gear; As the moving block slides within the arc-shaped track, the rotating gear rolls on the arc-shaped rack.

[0008] In one possible implementation, based on the above technical solutions, the driving mechanism includes: A push plate is fixed to the movable rod and located on the outside of the mounting plate; A drive cylinder is disposed on the outside of the mounting plate and is used to push the push plate; A retaining component, disposed between the moving rod and the turntable, is used to unidirectionally restrict the movement of the moving rod; and A reset spring is disposed between the turntable and the clamping plate; When the retaining assembly restricts the movement direction of the moving rod, the moving rod can only move towards the bottle; the return spring is used to drive the clamp and the moving rod to return to their original position away from the bottle when the retaining assembly releases the restriction on the moving rod.

[0009] In one possible implementation, based on the above technical solutions, the retaining component includes: A ratchet is fixed to the movable rod and parallel to the movable rod; A pawl, disposed on the turntable, engages with the ratchet teeth; and A release component is provided on the turntable to drive the pawl to separate from the ratchet teeth; When the ratchet tooth engages with the pawl, the moving rod can only move in the direction of approaching the bottle.

[0010] In one possible implementation, based on the above technical solutions, the release component includes: A sliding frame is slidably mounted on the turntable, and the sliding direction of the sliding frame is parallel to the tooth width direction of the ratchet; the pawl is mounted on the sliding frame. A miniature cylinder is mounted on the turntable, and the piston rod of the miniature cylinder is connected to the sliding frame.

[0011] In one possible implementation, based on the above technical solutions, the push component includes: A push plate, fixed to the movable block and located outside the mounting plate; and A push cylinder is disposed on the outside of the mounting plate, with one end of the push cylinder hinged to the mounting plate and the other end hinged to the push plate.

[0012] In one possible implementation, in conjunction with the above technical solutions, a limiting plate is provided on the inner side of the two mounting plates. The limiting plate is located on the conveyor belt and is used to block the conveying of bottles. The movable block is located at one end of the arc-shaped track near the bottle feeding direction, and when the bottle is blocked by the limiting plate, the two clamps are directly opposite the bottle.

[0013] In one possible implementation, based on the above technical solutions, the middle part of the limiting plate protrudes towards the conveying direction of the conveyor belt, so that the position where the limiting plate blocks the bottle is V-shaped.

[0014] In one possible implementation, based on the above technical solutions, the mounting plate and the conveyor belt frame are detachably connected.

[0015] The beneficial effects of the bottle flipping structure provided in this application are as follows: Compared with the prior art, in this application, when the bottle moves with the conveyor belt between two clamping plates, the drive mechanism drives the moving rod to slide, so that the clamping plates approach the bottle and clamp it; then, the rotating component drives the turntable to rotate, and after the bottle flips 180°, the drive mechanism drives the moving rod to reset, so that the clamping plates release the bottle, allowing the bottle to continue to be conveyed after flipping; the active clamping and flipping method greatly improves the accuracy of bottle flipping, avoids the problem of bottles getting stuck due to limited internal space in the guide flipping channel, makes the bottle flipping process smoother, and prevents subsequent bottles from piling up due to the previous bottles getting stuck, thereby significantly improving the bottle production efficiency.

[0023] The bottle flipping structure provided in this application will now be described.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this application provides a bottle flipping structure, including two mounting plates 1, two turntables 2, two moving rods 3, two clamping plates 4, two sets of rotating components 5, and two sets of driving mechanisms 6.

[0025] Two mounting plates 1 are respectively set on both sides of the conveyor belt; two turntables 2 correspond one-to-one with the two mounting plates 1, and the turntables 2 are rotatably set on the mounting plates 1; two moving rods 3 correspond one-to-one with the two turntables 2 and are slidably connected to the turntables 2 along their own axes, with one end of the moving rod 3 located above the conveyor belt. Two clamping plates 4 correspond one-to-one with two moving rods 3 and are fixed at the ends of the moving rods 3 located above the conveyor belt; two sets of rotating components 5 are respectively set on two mounting plates 1 to drive the turntable 2 to rotate; two sets of driving mechanisms 6 are respectively set on two mounting plates 1 to drive the moving rods 3 to slide.

[0026] This embodiment provides a bottle flipping structure that, compared to existing technologies, allows the following: when a bottle moves with the conveyor belt between two clamping plates 4, the drive mechanism 6 drives the moving rod 3 to slide, causing the clamping plates 4 to approach and clamp the bottle. Subsequently, the rotating component 5 drives the turntable 2 to rotate, and after the bottle flips 180°, the drive mechanism 6 drives the moving rod 3 to reset, causing the clamping plates 4 to release the bottle, allowing the bottle to continue being conveyed after flipping. This active clamping and flipping method greatly improves the accuracy of bottle flipping, avoids the problem of bottles getting stuck due to limited space inside the guide flipping channel, and makes the bottle flipping process smoother, preventing subsequent bottles from piling up due to previous bottles getting stuck, thereby significantly improving bottle production efficiency.

[0027] Furthermore, the design of this structure allows it to adapt to bottles of different sizes and shapes; by adjusting the parameters of the drive mechanism 6, the clamping force of the clamping plate 4 on the bottle can be changed to meet the requirements of different bottles.

[0028] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The mounting plate 1 has an arc-shaped track 11, with the middle of the arc-shaped track 11 being higher than the two ends; the bottle flipping structure also includes two moving blocks 7 and two sets of pushing components 8; Two movable blocks 7 correspond one-to-one with two arc-shaped tracks 11 and are slidably connected to the arc-shaped tracks 11 in the direction of conveyor belt transport; two sets of pushing components 8 are respectively set on two mounting plates 1 to drive the movable blocks 7 to slide in the arc-shaped tracks 11; when the movable blocks 7 slide from one end of the arc-shaped track 11 near the bottle feeding direction to the other end, the rotating component 5 drives the turntable 2 to rotate automatically 180°.

[0029] When the pushing component 8 drives the moving block 7 to slide within the arc-shaped track 11, due to the special shape of the arc-shaped track 11, the moving block 7 can lift the bottle during the flipping process via the moving rod 3 and the clamping plate 4, preventing damage to the bottle during the flipping process. Simultaneously, as the moving block 7 slides from one end of the arc-shaped track 11 near the bottle feeding direction to the other end, the rotating component 5 automatically flips the bottle, improving the automation level of the production process, reducing manual intervention, and lowering labor costs.

[0030] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The rotating assembly 5 includes a rotating gear 51 and an arc-shaped rack 52; the rotating gear 51 is coaxially fixed to the outside of the turntable 2; the arc-shaped rack 52 is fixed inside the arc-shaped track 11 and is always meshed with the rotating gear 51; when the moving block 7 slides inside the arc-shaped track 11, the rotating gear 51 rolls on the arc-shaped rack 52.

[0031] The gear and rack transmission has high transmission accuracy. When the moving block 7 slides in the arc track 11, the rotating gear 51 rolls on the arc rack 52, which can accurately convert the movement of the moving block 7 into the rotation of the turntable 2, so that the rotation angle of the turntable 2 can be precisely controlled, ensuring that the bottle can accurately complete the 180° flip and improving the accuracy of the flip.

[0032] Furthermore, rack and pinion drives offer superior stability and reliability. Because the meshing between the gears and rack is continuous, they can withstand larger loads and are less prone to slippage or tooth disengagement. This allows the rotating component 5 to maintain stable performance during long-term operation, reducing equipment maintenance costs and downtime.

[0033] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The drive mechanism 6 includes a push plate 61, a drive cylinder 62, a holding assembly 63, and a return spring 64; the push plate 61 is fixed on the moving rod 3 and located on the outside of the mounting plate 1; the drive cylinder 62 is located on the outside of the mounting plate 1 and is used to push the push plate 61; the holding assembly 63 is located between the moving rod 3 and the turntable 2 and is used to unidirectionally restrict the movement of the moving rod 3; the return spring 64 is located between the turntable 2 and the clamping plate 4. When the retaining component 63 restricts the movement direction of the moving rod 3, the moving rod 3 can only move towards the bottle; the return spring 64 is used to drive the clamp 4 and the moving rod 3 to return to their original positions away from the bottle when the retaining component 63 removes the restriction on the moving rod 3.

[0034] When the drive cylinder 62 pushes the push plate 61, the moving rod 3 can only approach the bottle under the restriction of the holding component 63, which avoids the situation where the moving rod 3 accidentally moves back during the clamping process, resulting in the bottle not being clamped securely; and when the moving block 7 moves, the push plate 61 separates from the drive cylinder 62. At this time, the moving rod 3 is restricted by the holding component 63 and remains stationary, which improves the clamping and flipping stability of the bottle by the clamping plate 4.

[0035] After the bottle is flipped, the retaining component 63 releases the restriction on the moving rod 3, and the return spring 64 drives the moving rod 3 to return to its original position, so that the clamping plate 4 releases the flipped bottle and enables the continued conveying of the bottle.

[0036] like Figures 3 to 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The retaining component 63 includes a ratchet 631, a pawl 632, and a release component; the ratchet 631 is fixed to the moving rod 3 and is parallel to the moving rod 3; the pawl 632 is disposed on the turntable 2 and engages with the ratchet 631; the release component is disposed on the turntable 2 and is used to drive the pawl 632 to separate from the ratchet 631; wherein, when the ratchet 631 and the pawl 632 are engaged, the moving rod 3 can only move in the direction closer to the bottle.

[0037] As the drive cylinder 62 pushes the push plate 61 to move the moving rod 3 closer to the bottle, the engagement of the ratchet 631 and the pawl 632 prevents the moving rod 3 from accidentally retracting, ensuring that the clamping plate 4 can firmly hold the bottle. Even under external interference, the moving rod 3 will not easily loosen, thereby improving the reliability of the bottle flipping process.

[0038] When the release component causes the pawl 632 to separate from the ratchet 631, the moving rod 3 can smoothly return to its original position away from the bottle under the action of the return spring 64. The controllable one-way restriction and release function makes the operation of the drive mechanism 6 more flexible and convenient, and improves production efficiency.

[0039] like Figures 3 to 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The release component includes a sliding frame 633 and a miniature cylinder 634; the sliding frame 633 is slidably mounted on the turntable 2, and the sliding direction of the sliding frame 633 is parallel to the tooth width direction of the ratchet 631; the pawl 632 is mounted on the sliding frame 633; ​​the miniature cylinder 634 is mounted on the turntable 2, and the piston rod of the miniature cylinder 634 is connected to the sliding frame 633.

[0040] When the piston rod of the miniature cylinder 634 extends or retracts, it drives the sliding frame 633 to slide, thereby causing the pawl 632 to separate from or engage with the ratchet 631. Precise control ensures that the retaining assembly 63 can accurately perform the unidirectional restraint and release functions of the moving rod 3. Moreover, the structure is compact, occupies little space, and will not have a significant impact on the layout of the entire bottle-flipping structure, which is conducive to the miniaturization and integration of the equipment.

[0041] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The pushing assembly 8 includes a pushing plate 81 and a pushing cylinder 82; the pushing plate 81 is fixed on the moving block 7 and located on the outside of the mounting plate 1; the pushing cylinder 82 is located on the outside of the mounting plate 1, with one end of the pushing cylinder 82 hinged to the mounting plate 1 and the other end hinged to the pushing plate 81.

[0042] The articulated connection of the push cylinder 82 provides it with a degree of flexibility when pushing the push plate 81, allowing it to adapt to the shape of the arc track 11 and ensuring smooth sliding of the moving block 7 within the track. Simultaneously, the articulated connection reduces friction and impact during the pushing process, extending the service life of the push assembly 8.

[0043] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Limiting plates 9 are provided on the inner side of the two mounting plates 1. The limiting plates 9 are located on the conveyor belt and are used to block the conveying of bottles. The moving block 7 is located at one end of the arc track 11 near the bottle feeding direction, and when the bottle is blocked by the limiting plate 9, the two clamping plates 4 are directly opposite the bottle.

[0044] The limiting plate 9 is designed to position the bottle, accurately blocking it in the appropriate position so that the clamping plate 4 can accurately clamp the bottle, improving the accuracy and efficiency of bottle flipping and avoiding situations where the clamping plate 4 cannot clamp the bottle or cannot clamp it securely due to inaccurate bottle position.

[0045] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The middle part of the limiting plate 9 protrudes towards the conveying direction of the conveyor belt, so that the position of the limiting plate 9 blocking the bottle is V-shaped.

[0046] The V-shaped structure can better position and guide the bottle. When the bottle is conveyed to the limiting plate 9, the V-shaped structure can guide the bottle to automatically adjust its position and stop accurately in the middle of the two clamping plates 4. This further improves the accuracy and stability of the clamping plates 4 in gripping the bottle and reduces the possibility of gripping failure or bottle damage caused by bottle position deviation.

[0047] In addition, the V-shaped structure can also increase the blocking effect of the limiting plate 9 on the bottle. Since the two sides of the V-shaped structure can generate a certain lateral pressure on the bottle, the bottle is more stable when blocked and is not easy to shake or deviate, which helps to improve the reliability and efficiency of the entire bottle flipping process.

[0048] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Mounting plate 1 is detachably connected to the conveyor belt frame via multiple bolts.

[0049] During the installation and commissioning of the equipment, the detachable connection allows the mounting plate 1 to be easily installed on the conveyor belt frame, and its position can be adjusted according to actual needs. It also facilitates the subsequent inspection, maintenance and replacement of various components on the mounting plate 1.

[0050] The above are merely preferred embodiments of this application and are not intended to limit this application.
