Description

Technical Field

[0001] The present invention relates to a capping device, and particularly to a technique for an aluminum film cap to fall onto a bottle mouth. Background Art

[0002] In the prior art, an aluminum film cap can be used to seal a bottle mouth. Before the aluminum film cap is combined with the bottle mouth, a three-dimensional aluminum film cap needs to be obtained by stamping an aluminum film. The flat circular aluminum film is stamped into an aluminum film cap with an overall disc-shaped structure. The middle of the aluminum film cap is a circular structure, and the edge is a skirt structure perpendicular to its middle part. The technique of adding an aluminum film cap to a bottle mouth is implemented in a linear capping manner. The bottle moves forward on a straight conveying path. When passing through the output end of the cap supply component, the aluminum film cap is dragged by the bottle mouth and finally separated from the cap supply component. The aluminum film cap falls onto the bottle mouth by its own weight, thus completing the capping operation of the aluminum film cap.

[0003] In this capping technique, any one conveying path can only serve the capping operation of the same batch of bottles on this conveying path. There is an upper limit to the speed of conveying bottles on the conveying path because there is an upper limit to the output of the cap supply component. That is, when a previous aluminum film cap is output, a subsequent aluminum film cap needs a period of time to reach the output end of the cap supply component. If the speed of conveying bottles is too fast, some bottles will pass through the output end of the cap supply component without an aluminum film cap being paired with their bottle mouths, and the capping rhythm does not match the speed of conveying bottles, resulting in the situation that some bottle mouths do not have aluminum film caps. Therefore, in the prior art, the capping efficiency of a single conveying path is limited. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to improve the capping efficiency of a single conveying path, and thus a capping device is obtained.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: The capping device includes a rotary conveying component, a linear input component, a linear output component, a lid supply component I, and a lid supply component II. The linear input component is provided with a linear conveying path I, and the linear output component is provided with a linear conveying path II. The rotary conveying component is provided with an arc-shaped conveying path I. One end of the arc-shaped conveying path I is connected to the linear conveying path I, and the other end of the arc-shaped conveying path I is connected to the linear conveying path II. The lid supply component I and the lid supply component II are both located above the arc-shaped conveying path I. The lid supply component I and the lid supply component II are sequentially distributed along the arc-shaped conveying path I, and the lid supply component I is located upstream of the lid supply component II. The output directions of the lid supply component I and the lid supply component II are both tangent to the arc-shaped conveying path I. The rotary conveying component includes a handling component I, a handling component II, a guard plate I, a cylindrical cam, a turntable I, and a driving component. The turntable I is connected to the driving component and is driven to rotate unidirectionally. The cylindrical cam is stationary relative to the driving component. The cylindrical cam is provided with a curve groove I and a curve groove II. The curve groove I and the curve groove II are distributed around the rotation center line of the turntable I. The handling component I and the handling component II are distributed on the turntable I in an alternating manner. The handling component I is provided with a sliding sleeve, a guide rod, a load platform I, and a bearing I. The sliding sleeve is fixedly connected to the turntable I. The load platform I and the bearing I are both installed on the guide rod. The guide rod is slidably connected to the sliding sleeve. The bearing I is embedded in the curve groove I. The handling component II is provided with a sliding sleeve, a guide rod, a load platform II, and a bearing II. The sliding sleeve is fixedly connected to the turntable I. The load platform II and the bearing II are both installed on the guide rod. The guide rod is slidably connected to the sliding sleeve. The bearing II is embedded in the curve groove II. The movement ranges of the load platform I and the load platform II intersect with the arc-shaped conveying path I. The guard plate I is located outside the arc-shaped conveying path I. The curve groove I is provided with a translation section I and a lifting section I, and the translation section I and the lifting section I are connected. The curve groove II is provided with a translation section II and a lifting section II, and the translation section II and the lifting section II are connected. The lifting section I and the lifting section II are staggeredly distributed in the circumferential direction around the cylindrical cam. The lifting section I is located below the output end of the lid supply component I, and the lifting section II is located below the output end of the lid supply component II.

[0006] This technical solution inserts a horizontal arc-shaped conveying path into the original conveying path of the bottle. The arc-shaped conveying path is constructed based on a rotary conveying structure. On the rotary conveying structure, there are two sets of handling components arranged alternately. The two sets of handling components can move independently according to the corresponding curve grooves given by the cylindrical cam. After the two sets of handling components receive the bottles, they can generate relatively independent movements between any two adjacent bottles. For example, one bottle is lifted while the other bottle remains at the original conveying height. This technical solution achieves the technical effect of controlling the independent movement between adjacent bottles, so that the bottles entering the arc-shaped conveying path are naturally divided into two groups. Thanks to the two lid supply components distributed before and after along the arc-shaped conveying path, the workstations where adjacent bottles are lifted are separately arranged and correspond to the positions of the two lid supply components. When the bottle is lifted and passes through the output end of the lid supply component, it can obtain an aluminum film lid from the lid supply component. The movement speeds of the bottles on the linear conveying path I, the arc-shaped conveying path I, and the linear conveying path II remain unchanged. However, the movement states of the handling component I and the handling component II driven by the cylindrical cam are independent of each other and coordinated with each other, so that the bottles on the handling component I and the handling component II can continue the original conveying path, that is, without diverging, and maintain the original movement speed, and can obtain the technical effect of lifting movement by in-channel grouping control within the same conveying path. This technical solution significantly improves the lid-covering efficiency of the original conveying path as a whole.

[0007] In order to be able to match a faster bottle conveying speed, that is, high production, the present invention provides a transition structure between the linear conveying path and the arc-shaped conveying path. The function of this transition structure is to reduce the angular velocity of the bottle when turning, because too high an angular velocity is not conducive to the smooth connection of the bottle between different paths and is very likely to cause the situation of bottle jamming due to too large an angular velocity. This transition structure for reducing the angular velocity also affects the design requirements for the minimum radius of the arc-shaped conveying path I. This is because the transition structure increases the design freedom of the connection relationship between the linear conveying path and the arc-shaped conveying path I. The position design of the linear conveying path I and the linear conveying path II, that is, the aforementioned linear conveying path relative to the arc-shaped conveying path I, becomes flexible, thus providing extremely strong adaptability in terms of site layout for the entire technical solution. The transition structure is specifically as follows. The lid-covering device includes a rotary input component and a rotary output component. The rotary input component is provided with an arc-shaped conveying path II. The rotary output component is provided with an arc-shaped conveying path III. One end of the arc-shaped conveying path II is connected to the linear conveying path I, and the other end of the arc-shaped conveying path II is connected to one end of the arc-shaped conveying path I. One end of the arc-shaped conveying path III is connected to the linear conveying path II, and the other end of the arc-shaped conveying path III is connected to the other end of the arc-shaped conveying path I. This transition structure is also beneficial to reducing the radius of the arc-shaped conveying path II, making the entire lid-covering device have the advantage of compact volume.

[0008] In order to match the requirements for the spacing between bottles when the handling component I and the handling component II receive the bottles, a grouping component is provided on the linear input component. The grouping component includes a guardrail provided on one side of the linear conveying path I and a variable pitch screw provided on the other side of the linear conveying path I. The grouping component is located at the end of the linear conveying path I. The grouping component can re-regularize the bottles that are not arranged at equal intervals on the linear input component into a state of equal interval arrangement.

[0009] As a preference of this technical solution, the extending direction of the linear conveying path I coincides with the extending direction of the linear conveying path II. With this structure, consistent working conditions are provided for the conveying process of the bottles, which is convenient for the entire capping device to operate in the best working state.

[0010] In this technical solution, although the distances of the carrier I and the carrier II relative to the turntable I will change, that is, their spatial positions will change, it is necessary to ensure that the carrier I and the carrier II maintain the same spatial attitude relative to the turntable I, especially that neither of them can generate a self-rotation action. Otherwise, they cannot be connected front and back on the conveying path, and it is very likely that the bottles will get stuck on the carrier I and the carrier II. For this reason, this technical solution also proposes improvements to the specific structures of the handling component I and the handling component II. The handling component I is provided with two guide rods and two sliding sleeves. The handling component I is also provided with an L-shaped bearing seat I. One end of the guide rod is fixedly connected to the carrier I, and the other end of the guide rod is connected to the bearing seat I. The bearing I is installed on the bearing seat I. The two guide rods of the handling component I are arranged in sequence in the radial direction along the rotation center line of the turntable I. The handling component II is provided with two guide rods and two sliding sleeves. The handling component II is also provided with an L-shaped bearing seat II. One end of the guide rod is fixedly connected to the carrier II, and the other end of the guide rod is connected to the bearing seat II. The bearing II is installed on the bearing seat II. The two guide rods of the handling component II are arranged in sequence in the radial direction along the rotation center line of the turntable I. Both handling components have two guide rods each, and the guide rods are distributed radially. This structure can prevent self-rotation actions; at the same time, the structure of the two guide rods helps to improve the structural strength.

[0011] The structural designs of the handling component I and the handling component II are based on the same design concept, and they are in the same working area, only with differences in the working time sequence. Therefore, their specific structures can adopt a common design to achieve interchangeability and compatibility of parts. For this reason, the length of the guide rod of the handling component I is equal to the length of the guide rod of the handling component II, and the installation directions of the bearing seat I and the bearing seat II are opposite. With such a design, the handling component I and the handling component II can share parts, which is beneficial to reducing production costs.

[0012] The present invention adopts the above technical solution: the capping device controls the marshalling in the track, and two capping stations are arranged on the conveying path of the bottles. The bottles perform the double-station capping operation while maintaining the original conveying speed and continuing the original conveying path, thereby improving the capping efficiency of a single conveying path.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The first embodiment of the present invention is as shown in Figure 1 , 2 , 3, 4, 5, 6, 7, 8.

[0023] The capping device includes a rotary conveying component 1, a linear input component 2, a rotary input component 3, a linear output component 4, a rotary output component 5, a lid supply component I 6, a lid supply component II 7, and a frame.

[0024] The rotary conveying component 1 includes a handling component I 8, a handling component II 9, a guard plate I 10, a cylindrical cam 11, a turntable I 12, and a driving component. The guard plate I 10, the cylindrical cam 11, and the driving component are all fixedly installed on the frame, and the guard plate I 10, the cylindrical cam 11, and the driving component are all stationary relative to the frame. The turntable I 12 is movably installed on the frame, and there is a transmission connection between the turntable I 12 and the driving component. The driving component can drive the turntable I 12 to rotate unidirectionally. After the turntable I 12 rotates, its spatial attitude changes accordingly, but the relative position of the turntable I 12 on the frame remains unchanged.

[0025] A through hole is provided in the middle of the cylindrical cam 11 to facilitate the transmission shaft structure on the turntable I 12 to pass through. After installation, the turntable I 12 is located in the middle position of the cylindrical cam 11, and the rotation center line of the turntable I 12 coincides with the center line of the cylindrical cam 11. There are two curved grooves on the cylindrical cam 11, namely a curved groove I 13 and a curved groove II 14. The curved groove I 13 and the curved groove II 14 are both distributed on the side surface of the cylindrical cam 11, and both are groove structures on the side surface of the cylindrical cam 11 that surround the center line of the cylindrical cam 11. Therefore, the curved groove I 13 and the curved groove II 14 are distributed around the rotation center line of the turntable I 12. The curved groove I 13 is provided with a translation section I 15 and a lifting section I 16, and the translation section I 15 and the lifting section I 16 are connected end to end, that is, one end of the translation section I 15 is connected to one end of the lifting section I 16, and the other end of the lifting section I 16 is connected to the other end of the translation section I 15. The curved groove II 14 is provided with a translation section II 17 and a lifting section II 18, and the translation section II 17 and the lifting section II 18 are connected end to end, that is, one end of the translation section II 17 is connected to one end of the lifting section II 18, and the other end of the lifting section II 18 is connected to the other end of the translation section II 17. The overall structures of the curved groove I 13 and the curved groove II 14 are the same, and the difference lies in the different distribution angles of the two on the cylindrical cam 11, and the two are staggeredly distributed in the circumferential direction around the cylindrical cam 11. This staggered distribution feature is manifested in the staggered distribution of the lifting section I 16 and the lifting section II 18 in the circumferential direction around the cylindrical cam 11, because in the direction parallel to the center line of the cylindrical cam 11, the lifting section I 16 protrudes from the translation section I 15, the lifting section II 18 protrudes from the translation section II 17, and the length of the translation section I 15 is greater than the length of the lifting section I 16, and the length of the translation section II 17 is greater than the length of the lifting section II 18.

[0026] The handling component I 8 and the handling component II 9 are alternately distributed on the turntable I 12 and arranged in a ring shape, and both the handling component I 8 and the handling component II 9 are located at the edge of the turntable I 12. The curved groove I 13 serves the handling component I 8, and the curved groove II 14 serves the handling component I 8. The movement beats of the handling component I 8 and the movement beats of the handling component II 9 are relatively independent, but the movement beats of the two are coordinated with each other and there is an associated relationship as a whole.

[0027] The handling assembly I 8 and the handling assembly II 9 adopt a common design, and the required parts can be interchangeable and compatible. The handling assembly I 8 is provided with a sliding sleeve, a guide rod, a load platform I 19, a bearing I 20, and a bearing seat I 21. The handling assembly I 8 has two slider mechanisms composed of a guide rod and a sliding sleeve. The sliding sleeve is fixedly connected to the turntable I 12, the guide rod is slidably connected to the sliding sleeve, the center line of the guide rod is parallel to the rotation center line of the turntable I 12, and the two guide rods of the handling assembly I 8 are arranged in sequence in the radial direction along the rotation center line of the turntable I 12. A positional relationship is formed between the guide rod and the turntable I 12, where one end of the guide rod is higher than the turntable I 12 and the other end is lower than the turntable I 12. The load platform I 19 is provided with a load surface for supporting the bottom of the bottle and a notch for restricting the bottle body. One end of the guide rod is fixedly connected to the load platform I 19, and the other end of the guide rod is connected to the bearing seat I 21. The bearing seat I 21 is integrally L-shaped, and it is provided with a long side part and a short side part, where the long side part is connected to the guide rod, and the short side part is used for installing the bearing I 20. The handling assembly II 9 is provided with a sliding sleeve, a guide rod, a load platform II 22, a bearing II 23, and a bearing seat II 24. The handling assembly II 9 has two slider mechanisms composed of a guide rod and a sliding sleeve. The sliding sleeve is fixedly connected to the turntable I 12, the guide rod is slidably connected to the sliding sleeve, the center line of the guide rod is parallel to the rotation center line of the turntable I 12, and the two guide rods of the handling assembly II 9 are arranged in sequence in the radial direction along the rotation center line of the turntable I 12. A positional relationship is formed between the guide rod and the turntable I 12, where one end of the guide rod is higher than the turntable I 12 and the other end is lower than the turntable I 12. The load platform II 22 is provided with a load surface for supporting the bottom of the bottle and a notch for restricting the bottle body. One end of the guide rod is fixedly connected to the load platform II 22, and the other end of the guide rod is connected to the bearing seat II 24. The bearing seat II 24 is integrally L-shaped, and it is provided with a long side part and a short side part, where the long side part is connected to the guide rod, and the short side part is used for installing the bearing II 23. The sliding sleeve, the guide rod, the load platform I 19, the bearing I 20, and the bearing seat I 21 of the handling assembly I 8 have the same structure and dimensions as the sliding sleeve, the guide rod, the load platform II 22, the bearing II 23, and the bearing seat II 24 of the handling assembly II 9 respectively, so the parts are compatible and can be interchanged.

[0028] The bearing I 20 is embedded in the curve groove I 13, and the bearing II 23 is embedded in the curve groove II 14. After the turntable I 12 moves, it drives the handling component I 8 and the handling component II 9 to move. The bearing I 20 is guided by the curve groove I 13 and gives a force to the guide rod, prompting the guide rod of the handling component I 8 to move relative to the sliding sleeve. Similarly, the bearing II 23 is guided by the curve groove II 14 and gives a force to the guide rod, prompting the guide rod of the handling component II 9 to move relative to the sliding sleeve. When the bearing I 20 is in the translation section I 15 and the bearing II 23 is in the translation section II 17, the carrier table I 19 and the carrier table II 22 are at the same height and at a lower height. At this time, the height where the carrier table I 19 and the carrier table II 22 are located is recorded as the reference height; when the bearing I 20 is in the lifting section I 16 and the bearing II 23 is in the lifting section II 18, the carrier table I 19 and the carrier table II 22 are at another same height and at a higher height. At this time, the height where the carrier table I 19 and the carrier table II 22 are located is recorded as the capping height. The capping height is greater than the reference height.

[0029] There are structural differences between the handling component I 8 and the handling component II 9. This difference is caused by the different installation directions. Specifically, the installation direction of the bearing seat I 21 is opposite to the installation direction of the bearing seat II 24. The reason for this difference is that in order to cope with the independence between the curve groove I 13 and the curve groove II 14, the curve groove I 13 is located above the curve groove II 14 under the working conditions. In order to enable the carrier table I 19 and the carrier table II 22 to be at the same reference height, the bearing seat I 21 and the bearing seat II 24 need to be assembled with opposite installation directions, so as to offset the negative impact of the distance between the curve groove I 13 and the curve groove II 14 on obtaining the reference height.

[0030] The carrier table I 19 and the carrier table II 22 perform a rotary motion. The space passed by the two is the annular motion range of the carrier table I 19 and the annular motion range of the carrier table II 22, and these two motion ranges are superimposed. The motion range of the carrier table I 19 is affected by the guidance of the lifting section I 16 and shows a bulge along the direction parallel to the rotation center line of the turntable I 12, forming a lifting action; similarly, the motion range of the carrier table II 22 is affected by the guidance of the lifting section II 18 and shows a bulge along the direction parallel to the rotation center line of the turntable I 12, forming a lifting action; the two bulges here are misaligned in the circumferential direction around the cylindrical cam 11, and this positional relationship corresponds to the misalignment relationship between the lifting section I 16 and the lifting section II 18.

[0031] The guard plate I 10 is located outside the motion ranges of the carrier table I 19 and the carrier table II 22, and is also located outside the convex structures of the motion ranges of the carrier table I 19 and the carrier table II 22. The guard plate I 10 is used to limit the bottle body and prevent the bottle body from detaching from the carrier table I 19 and the carrier table II 22.

[0032] The cover supply component I6 and the cover supply component II7 are both installed on the frame. After installation, the cover supply component I6 and the cover supply component II7 are located above the turntable I12. The lifting section I16 is located below the output end of the cover supply component I6, and the lifting section II18 is located below the output end of the cover supply component II7.

[0033] The moving range of the stage Ⅰ19 and the moving range of the stage Ⅱ22 are in the section next to the inner side of the guard plate Ⅰ10, which is the arc conveying path Ⅰ of the rotating conveying component 1. The center of the arc conveying path Ⅰ coincides with the rotation center line of the turntable Ⅰ12. The direction of the output end of the cover supply component Ⅰ6 and the direction of the output end of the cover supply component Ⅱ7 are both along the conveying direction of the arc conveying path Ⅰ, and the output direction of the cover supply component Ⅰ6 is perpendicular to the radius of the arc conveying path Ⅰ, and the output direction of the cover supply component Ⅱ7 is perpendicular to the radius of the arc conveying path Ⅱ, so the output direction of the cover supply component Ⅰ6 and the output direction of the cover supply component Ⅱ7 are tangent to the arc conveying path Ⅰ.

[0034] The rotating input component 3 is provided with a guard plate II and a turntable II. A bearing structure for receiving bottles is provided on the turntable II. The spacing of the bearing structures is equal to the distance between the loading platform I 19 and the loading platform II 22. The guard plate II is located outside the turntable II and is used to limit the bottles so that the bottles cannot escape from the bearing structure. During installation, the turntable I 12 and the turntable II are partially overlapped in the vertical direction, the guard plate I 10 extends above the turntable II, and the guard plate II extends above the turntable I 12. The turntable II also rotates in one direction, and the rotation direction of the turntable II is opposite to that of the turntable I 12. The motion range of the bearing structure of the turntable II is annular, and the section of the motion range next to the inner side of the guard plate II is the arc conveying path II of the rotating input component 3. The arc conveying path II is connected with the arc conveying path I, and the arc conveying path I can receive bottles from the arc conveying path II.

[0035] The rotating output component 5 is provided with a guard plate III and a turntable III. A bearing structure for receiving bottles is provided on the turntable III. The spacing of the bearing structure is equal to the distance between the loading platform I 19 and the loading platform II 22. The guard plate III is located outside the turntable III and is used to limit the bottles so that the bottles cannot be separated from the bearing structure. During installation, the turntable I 12 and the turntable III are partially overlapped in the vertical direction. The turntable III can be docked with the loading platform I 19 and the loading platform II 22. The guard plate I 10 extends above the turntable III and the guard plate III extends above the turntable I 12. The turntable III also rotates in one direction, and the rotation direction of the turntable III is opposite to that of the turntable I 12. The motion range of the bearing structure of the turntable III is annular, and the section of the motion range next to the inner side of the guard plate III is the arc conveying path III of the rotating output component 5. The arc conveying path III is connected with the arc conveying path I, and the arc conveying path III can receive bottles from the arc conveying path I.

[0036] The linear input component 2 is provided with a conveying chain and a grouping component. The grouping component is provided with a guardrail and a variable pitch screw. The conveying chain is distributed straight, the guardrail is distributed on one side of the conveying chain, and the variable pitch screw is located on the other side of the conveying chain. After the variable pitch screw rotates, it can adjust the spacing of the bottles along the conveying rhythm of the conveying chain. The guard plate II extends above the conveying chain, and the turntable II also extends above the conveying chain. Above the conveying chain is the linear conveying path I of the linear input component 2. The linear conveying path I is connected to the arc-shaped conveying path II, and the arc-shaped conveying path II can receive the bottles from the linear conveying path I. The grouping component is located at the end of the linear conveying path I, next to the arc-shaped conveying path II. The linear conveying output component is provided with a conveying chain, and the conveying chain is distributed straight. The guard plate II extends above the conveying chain, and the turntable III extends above the conveying chain. Above the conveying chain is the linear conveying path II of the linear conveying output component. The linear conveying path II is connected to the arc-shaped conveying path III, and the linear conveying path II can receive the bottles from the arc-shaped conveying path III. The extending direction of the linear conveying path I coincides with the extending direction of the linear conveying path II.

[0037] During use, the bottles will sequentially enter the linear conveying path I, the arc-shaped conveying path II, the arc-shaped conveying path I, the arc-shaped conveying path III, and the linear conveying path II. The bottles are forced to adjust the spacing by the grouping component at the end of the linear conveying path I. In this way, regardless of whether the bottles on the linear conveying path I are arranged at intervals, after being adjusted by the grouping component, the bottle spacing can be ensured to meet the conveying requirements of the rotary conveying component 1, the rotary input component 3, and the rotary output component 5. After the bottles enter the arc-shaped conveying path I, the bottles will be placed on the handling component I 8 and the handling component II 9. The cap supply component I 6 and the cap supply component II 7 are both located above the arc-shaped conveying path I.

[0038] When the bottles enter the arc-shaped conveying path I, the following actions will occur.

[0039] When the bearing Ⅰ20 of the transport component Ⅰ8 enters the lifting section Ⅰ16, the bottle on the loading platform Ⅰ19 is lifted and the bottle is at the capping height. After the bottle passes the output end of the capping component Ⅰ6, the bottle mouth pulls an aluminum film cover, and the aluminum film cover covers the bottle mouth; at this time, the bearing Ⅱ23 of the transport component Ⅱ9 adjacent to the transport component Ⅰ8 is in the translation section Ⅱ17, and the bottle on the loading platform Ⅱ22 is at the reference height, that is, the original conveying height of the bottle. When the bearing Ⅱ23 of the transport component Ⅱ9 enters the lifting section Ⅱ18, the bottle on the loading platform Ⅱ22 is lifted and the bottle is at the capping height. After the bottle passes the output end of the capping component Ⅱ7, the bottle mouth pulls an aluminum film cover, and the aluminum film cover covers the bottle mouth; at this time, the bearing Ⅰ20 of the transport component Ⅰ8 adjacent to the transport component Ⅱ9 is in the translation section Ⅰ15, and the bottle on the loading platform Ⅰ19 is at the reference height, that is, the original conveying height of the bottle. The two lifting actions are performed at separate distances, so that two capping operations can be obtained on the same conveying path, thereby significantly improving the work efficiency of the capping operation.

[0040] The arc conveying path I only occupies a part of the motion range of the loading platform I19 and the motion range of the loading platform II22, and the two intersect in space. Since the cover supply component I6 and the cover supply component II7 are distributed in sequence along the arc conveying path I and the cover supply component I6 is located upstream of the cover supply component II7, there is a timing feature between the adjacent loading platforms I19 and II22 that the bottles on the loading platform I19 are always lifted first and the bottles on the loading platform II22 are always lifted later. However, the two lifting actions can be generated synchronously or asynchronously on the entire arc conveying path I, depending on production needs. This embodiment adopts an asynchronous method. Before leaving the arc conveying path I, the bottles will return to the reference height, that is, the original conveying height, and finally the bottles with aluminum film caps will be output outward through the straight conveying path II.

[0041] The second embodiment of the present invention is different from the first embodiment in that the capping device is not provided with a rotating input component and a rotating output component, and the rotating conveying component is directly connected with the linear input component and the linear output component. In this embodiment, two guide plates need to be configured, one end of which extends above the turntable I, and the other end of which extends above the conveying chain of the linear input component 2, and one end of the other guide plate extends above the turntable I, and the other end of which extends above the conveying chain of the linear conveying output component. The function of the guide plate is to guide the bottle to leave the linear conveying path I and enter the arc conveying path I, or to guide the bottle to leave the arc conveying path I and enter the linear conveying path II.

[0042] In the above embodiments, the grouping component is provided for grouping operations when the bottles cannot obtain an effective arrangement spacing. In working conditions where the bottles can maintain a spacing, the structure of the grouping component can be omitted, thereby obtaining the other two embodiments.

[0043] In the above embodiments, the linear conveying path I and the linear conveying path II can also be provided by the same conveying chain, so that the extending directions of the two must coincide. Such a design can reduce the use of drive components and reduce the complexity of mechanical design. Thereby obtaining the other four embodiments.
