Description

Technical Field

[0001] This utility model relates to the field of cap and bottle installation in production lines, specifically to inline capping equipment. Background Technology

[0002] Currently, some manufacturers in the food, pharmaceutical, and daily chemical industries often use bottling to package their products. After the products are packaged into the bottles, caps need to be installed at the bottle openings to seal them tightly and prevent the products from coming off the bottle openings.

[0003] However, as production volume increases, the number of bottles used to hold the products also increases. If manual installation of caps and bottles continues, the speed of manual installation will gradually decrease as the total number of caps and bottles increases, leading to a decrease in overall installation efficiency and an increase in labor costs. To improve the installation efficiency of caps and bottles, a capping machine has emerged on the market that can automatically install caps and bottles together. Compared to manual installation, the capping machine can install caps and bottles much faster, and its installation speed remains constant even when installing a considerable number of caps and bottles, thus resulting in higher installation efficiency.

[0004] Furthermore, manufacturers may use only one size for the bottle and cap of their products. Therefore, capping equipment may need to be used to install caps and bottles of various sizes. In other words, the capping section of the capping equipment needs to be adjusted to accommodate the installation of caps and bottles of different sizes. Utility Model Content

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 7 A preferred embodiment of the inline capping device according to the present invention will be described in detail below. The inline capping device includes a device body 10, a bottle handling device 20, and a cap handling device 30, wherein the device body 10 forms an operating space 101. The bottle handling device 20 includes a bottle conveying member 21, which is installed in the operating space 101 of the device body 10, and the bottle conveying member 21 is provided with a bottle conveying channel, which moves within the operating space 101 to convey multiple bottles 900 into the operating space 101.

[0029] The cap processing device 30 includes at least one capping assembly 31, wherein each capping assembly 31 includes two capping drive members 311 and the same number of capping members 312 as the capping drive members 311. The two capping drive members 311 are arranged opposite to each other and spaced apart in the operating space 101 of the device body 10, and are both held above the bottle conveying member 21. In addition, the two capping drive members 311 are respectively arranged on both sides of the bottle conveying channel of the bottle conveying member 21. Each of the capping components 312 is rotatably mounted on a capping drive component 311, and each capping component 312 is positioned at a predetermined location near each bottle body 900 where a cap 800 is placed. In addition, each capping component 312 has a rotating part on its periphery, and each rotating part can drive the cap 800 placed on each bottle body 900 when the capping drive component 311 drives the capping component 312 to rotate, thereby completing the installation operation between the cap 800 and the bottle body 900.

[0030] Those skilled in the art will understand that the two capping members 312 mounted on the capping drive member 311 are positioned relative to each other and spaced apart due to the positional arrangement between the two capping drive members 311, so that when the bottle body 900 to be capped is conveyed in the bottle conveying channel of the bottle conveying member 21, the cap 800 of each bottle body 900 is conveyed between the two capping members 312 and engages with the rotating part of each capping member 312. Therefore, each capping drive member 311 is activated to drive each corresponding capping member 312 to rotate, thereby causing the rotating part of each capping member 312 to drive the cap 800 so that the cap 800 is installed on the bottle body 900.

[0031] In this way, when the inline capping device needs to install a considerable number of caps 800 and bottles 900, the bottle conveying member 21 conveys the caps 800 and bottles 900 to the capping assembly 31 of the cap processing device 30, and activates the capping drive member 311 of the capping assembly 31 to drive the capping member 312 to install the caps 800 onto the bottles 900. Compared with manual installation of the caps 800 and bottles 900, the installation speed of the capping assembly 31 in installing the caps 800 onto the bottles 900 does not slow down as the number of caps 800 and bottles 900 increases, thus the installation efficiency is higher and the labor cost is lower.

[0032] Preferably, the cap processing device 30 further includes a cap conveying member 32 for conveying the cap 800 to the operating space 101. Preferably, the cap conveying member 32 forms a cap conveying channel 321 along the conveying direction of the cap 800. The cap conveying channel 321 defines an inlet cap end and an outlet cap end at its two ends. The cap conveying channel 321 is arranged on the device body 10 such that the cap 800 is conveyed into the device body 10 by the inlet cap end and the cap 800 is conveyed out of the device body 10 by the outlet cap end. The outlet cap end of the cap conveying channel 321 is located in the operating space 101 and is positioned at a predetermined position above the bottle conveying channel of the bottle conveying member 21.

[0033] It is understood that the cap conveying member 32 conveys the cap 800 from the cap inlet end to the cap outlet end through the cap conveying channel 321. When the cap 800 is conveyed to the cap outlet end of the cap conveying channel 321, the cap 800 can be carried away by the bottle body 900 conveyed by the bottle conveying channel and detached from the cap conveying channel 321. Thus, the bottle body 900 with the cap 800 is conveyed to the cap screwing assembly 31 by the bottle conveying channel.

[0034] Preferably, the bottle conveying components 21 are all implemented to include a belt conveyor, and the bottle conveying channel of the bottle conveying component 21 is implemented as a moving channel formed by a conveyor belt.

[0035] Preferably, the cap processing device 30 further includes two cap-limiting assemblies 33. Preferably, each cap-limiting assembly 33 includes an elastic element 331, a baffle 332, and a fixing plate 333. The elastic element 331 is disposed between the baffle 332 and the fixing plate 333, with its two ends respectively connected to one side of the baffle 332 and one side of the fixing plate 333. The elastic element 331 is positioned at a predetermined height above the cap conveying channel 321. Each baffle 332 is movably disposed at a predetermined height above the cap conveying channel 321, near the cap-exit end of the cap conveying channel 321. Furthermore, the two baffles 332 are arranged opposite each other to form an opening, the opening being adjustable in size to fit the size of the cap 800 when the two baffles 332 move. The two fixing plates 333 are disposed on the cap conveying member 32.

[0036] Preferably, the elastic element 331 is implemented as a torsion spring.

[0037] Understandably, when the cap transmission channel 321 transmits the cap 800 through the cap outlet end, each cap 800 pushes the two baffles 332 under the transmission action of the cap transmission channel 321, causing the ends of the two baffles 332 connected to the elastic element 331 to move away from each other, thereby adjusting the size of the opening to gradually fit the size of the cap 800. Due to the action of the elastic element 331, the cap 800 is clamped by the two baffles 332 at the cap outlet end of the cap transmission channel 321. At this time, at least half of the structure of the cap 800 is detached from the cap transmission channel 321, which causes the cap 800 to gradually tilt under the action of gravity, and the tilted cap 800 is located on the transmission path of the bottle body 900. In this way, when the bottle conveying member 21 conveys the bottle body 900 through the inclined cap 800, the top of the bottle body 900 acts on the cap 800 and carries the cap 800 away. At this time, the top of the bottle body 900 is equipped with the cap 800, so that the cap screwing assembly 31 can install the cap 800 onto the bottle body 900.

[0038] Preferably, the cover processing device 30 further includes a cover channel adjustment component 34, which is used to adjust the channel size for the cover 800 transmission so that covers 800 of different sizes can be transmitted sequentially by the cover transmission channel 321, thereby preventing the covers 800 from blocking the cover transmission channel 321.

[0039] Preferably, the cover channel adjustment assembly 34 includes at least one drive unit 341, two movable plates 342, and a cover plate 343, wherein each drive unit 341 is mounted on the cover transfer member 32. The two movable plates 342 are arranged opposite to each other and spaced apart at a predetermined height on two sides of the cover transfer channel 321, and an adjustment opening is formed between the two movable plates 342, which can be adjusted to accommodate the size of the cover 800. Furthermore, each movable plate 342 is driven and movably mounted on the drive unit 341, and the two movable plates 342 can be driven by the drive unit 341 to move towards and away from each other to adjust the size of the adjustment opening. The cover plate 343 is installed on the cover conveying member 32 and is located at a predetermined position above the two moving plates 342 to form a sealed channel with the two moving plates 342, so that each cover 800 can only be conveyed into the cover conveying channel 321 through the cover inlet end and out through the cover outlet end.

[0040] It is understood that the drive unit 341 is activated to drive the two moving plates 342 to move towards or away from each other to adjust the size of the adjustment port, thereby adapting the adjustment port to the size of a single cover 800, and adjusting the width of the cover transmission channel 321. When the cover transmission channel 321 needs to be used to transmit two different sizes of covers 800 sequentially, the cover channel adjustment component 34 can adjust the channel width used for the movement of the covers 800 to adapt to the different sizes of covers 800, so that a single cover 800 can be transmitted sequentially by the cover transmission channel 321, thereby avoiding two or more covers 800 blocking each other and preventing the cover transmission channel 321 from continuing to transmit covers 800.

[0041] It should be added that the fixing plate 333 of each of the limiting cover components 33 is mounted on a movable plate 342, and the two fixing plates 33 mounted on the movable plate 342 are kept in opposite and spaced-apart positions.

[0042] In a specific example, the number of drive units 341 is set to one, wherein the drive unit 341 includes a drive component 3411 and a linkage component 3412. Preferably, the linkage component 3412 includes a linkage guide rail 34121, a linkage screw 34122, and two linkage sliders 34123. The linkage guide rail 34121 is disposed on the side of the cover plate 343 near the cover transmission channel 321 and above the two moving plates 342. The linkage screw 34122 is driven to rotate and is mounted on the drive end of the drive component 3411, and the linkage screw 34122 is provided with two threaded portions with different directions of rotation. The two linkage sliders 34123 are respectively threaded to the two threaded portions of the linkage screw 34122, and both linkage sliders 34123 are movably connected to the linkage guide rail 34121. The two linkage sliders 34123 can move towards or away from each other when the driving member 3411 drives the linkage screw 34122. Furthermore, each of the two linkage sliders 34123 is also connected to a movable plate 342, so that when the two linkage sliders 34123 move towards or away from each other, the two movable plates 342 are driven to move towards or away from each other.

[0043] Preferably, the cover plate 343 has a cover portion and a pressing portion connected to the cover portion, wherein the cover portion of the cover plate 343 is disposed at a predetermined position above the two moving plates 342. The pressing portion of the cover plate 343 is disposed above the bottle conveying member 21, and the extending direction of the pressing portion is parallel to the direction in which the bottle conveying member 21 conveys the bottle body 900, so that when the bottle body 900 moves the caps 800, the pressing portion of the cover plate 343 can press against each cap 800, so that each cap 800 is properly positioned on the bottle body 900, preventing the caps 800 from being installed on the bottle body 900 in an inclined position.

[0044] In a modified embodiment, the number of drive units 341 is set to two, and both drive units 341 are implemented to include telescopic cylinders, wherein the two telescopic cylinders are respectively installed on both sides of the cover transfer member 32, and each moving plate 342 is respectively installed on the telescopic end of one of the telescopic cylinders, so that when each telescopic cylinder is activated, the two moving plates 342 can be driven by the telescopic cylinder to move towards or away from each other to adjust the size of the adjustment port, thereby adjusting the width of the cover transfer channel 321.

[0045] Preferably, the cap processing device 30 further includes a cap supply member 35, wherein the cap supply member 35 is disposed adjacent to the cap conveying member 32, and the cap supply member 35 has a cap supply space 3501 for storing the conveyed cap 800, and the cap supply member 35 is further provided with a supply channel for connecting to the cap inlet end of the cap conveying channel 321, for supplying the cap 800 in the cap supply space 3501 to the cap conveying channel 321 of the cap conveying member 32.

[0046] It is worth mentioning that when a considerable number of caps 800 are stored in the cap supply space 3501 of the cap supply member 35, the orientation of the opening of most of the caps 800 is not determined. Therefore, during the process of supplying the caps 800 from the supply channel of the cap supply member 35 to the cap transmission channel 321, the cap supply member 35 can determine the orientation of the opening of the caps 800 downwards by vibration. The caps 800 transmitted by the supply channel push the caps 800 in the cap transmission channel 321, allowing each cap 800 to move from the cap inlet end to the cap outlet end of the cap transmission channel 321. This allows the top of the bottle 900 transmitted by the bottle transmission member 21 to abut against the inner wall of the cap opening of the cap 800, thereby causing the cap 800 to detach from the cap transmission channel 321. Preferably, the cap supply member 35 includes a cap vibrating disc.

[0047] Preferably, the capping assembly 31 further includes a transmission member 313. Preferably, the transmission member 313 includes a transmission guide rail 3131, a transmission screw 3132, a transmission drive member 3133, a first transmission slider 3134, and a second transmission slider 3135. The transmission guide rail 3131 is mounted in the operating space 101 of the device body 10. The transmission screw 3132 is driven to rotate and is mounted on the transmission drive member 3133. The transmission screw 3132 has a positive thread portion and a negative thread portion with the opposite thread direction to the positive thread portion. The first transmission slider 3134 is threadedly connected to the positive thread portion of the transmission screw 3132 and is movably connected to the transmission guide rail 3131. The second transmission slider 3135 is threadedly connected to the negative thread portion of the transmission screw 3132 and is movably connected to the transmission guide rail 3131. Furthermore, the first transmission slider 3134 and the second transmission slider 3135 are each connected to one of the cap-screwing drive members 311, and the first transmission slider 3134 and the second transmission slider 3135 can move towards or away from each other along the axial direction of the transmission screw 3132 when the transmission drive member 3133 drives the transmission screw 3132, so that the two cap-screwing drive members 311 respectively mounted on the first transmission slider 3134 and the second transmission slider 3135 can move towards or away from each other along the axial direction of the transmission screw 3132, thereby adjusting the distance between the two cap-screwing members 312 mounted on the two cap-screwing drive members 311. Preferably, the cap-screwing drive member 311 and the transmission drive member 3133 are implemented to include a drive motor.

[0048] It should be noted that when the in-line capping device needs to install caps 800 of different specifications onto the bottle body 900, the transmission drive 3133 is activated to drive the transmission screw 3132. Due to the limiting effect of the transmission guide rail 3131, the first transmission slider 3134 and the second transmission slider 3135 move towards or away from each other along the axial direction of the transmission screw 3132 on the transmission guide rail 3131, thereby adjusting the distance between the first transmission slider 3134 and the second transmission slider 3135. This adjustment of the distance between the two capping drive 311s, in turn, adjusts the distance between the two capping parts 312 to fit the specifications and dimensions of the caps 800 on the bottle body 900. In other words, the in-line capping device can simultaneously move the two capping parts 312 to bring them closer or further apart, thereby installing caps 800 of different specifications onto the bottle body 900.

[0049] More preferably, the bottle handling device 20 further includes at least one bottle rotating assembly 22, wherein each bottle rotating assembly 22 includes two bottle rotating drive members 221 and the same number of bottle rotating parts 222 as the bottle rotating drive members 221. The two bottle rotating drive members 221 are arranged opposite to and spaced apart in the operating space 101 of the device body 10, and are respectively arranged on both sides of the bottle transport channel of the bottle transport member 21. Each bottle rotating part 222 is driven to rotate and is mounted on one of the bottle rotating drive members 221, and each bottle rotating part 222 is arranged at a predetermined position close to each bottle body 900. In addition, each bottle rotating part 222 is provided with a rotating part on its circumference. Each rotating part can drive each bottle body 900 when the bottle rotating drive member 221 drives the bottle rotating part 222 to rotate, thereby further accelerating the installation between the cap 800 and the bottle body 900, thereby improving the installation efficiency.

[0050] Further preferably, the rotating bottle assembly 22 further includes a driving member 223. Preferably, the driving member 223 includes a driving guide rail 2231, a driving screw 2232, a driving drive member 2233, a first driving slider 2234, and a second driving slider 2235, wherein the driving guide rail 2231 is mounted on the device body 10. The driving screw 2232 is driven to rotate and is mounted on the driving drive member 2233, and the driving screw 2232 has a forward thread portion and a reverse thread portion with the opposite thread direction to the forward thread portion. The first driving slider 2234 is threadedly connected to the forward thread portion of the driving screw 2232, and the first driving slider 2234 is movably connected to the driving guide rail 2231. The second driving slider 2235 is threadedly connected to the reverse thread portion of the driving screw 2232, and the second driving slider 2235 is movably connected to the driving guide rail 2231. Furthermore, the first driving slider 2234 and the second driving slider 2235 are respectively connected to one of the bottle-turning drive members 221, and the first driving slider 2234 and the second driving slider 2235 can move towards or away from each other along the axial direction of the driving screw 2232 when the driving drive member 2233 drives the driving screw 2232, so that the two bottle-turning drive members 221 respectively mounted on the first driving slider 2234 and the second driving slider 2235 can move towards or away from each other along the axial direction of the driving screw 2232, thereby adjusting the distance between the two bottle-turning members 222 mounted on the two bottle-turning drive members 221.

[0051] It should be noted that when the inline capping device needs to install bottles 900 of different specifications with caps 800, the driving component 2233 is activated to drive the driving screw 2232. Due to the limiting effect of the driving guide rail 2231, the first driving slider 2234 and the second driving slider 2235 move towards or away from each other along the axial direction of the driving screw 2232 on the driving guide rail 2231, thereby adjusting the distance between the first driving slider 2234 and the second driving slider 2235. This, in turn, adjusts the distance between the two bottle-turning driving components 221, and consequently, adjusts the distance between the two bottle-turning components 222 to fit the specifications of the bottle 900. In other words, the inline capping device can simultaneously move the two bottle-turning components 222 to bring them closer or further apart, thereby rotating bottles 900 of different specifications to install with the cap 800. Furthermore, both the bottle-rotating drive 221 and the driving drive 2233 are implemented with a drive motor.

[0052] In one embodiment, the number of the bottle rotating assembly 22 and the capping assembly 31 are both set to three, and the three bottle rotating assemblies 22 and the three capping assemblies 31 are evenly arranged in the operating space 101 along the direction of transporting the bottle body 900 through the bottle transport channel of the bottle transport member 21. Each bottle rotating assembly 22 corresponds to one capping assembly 31, so that the capping assembly 31 can complete the installation operation between the three caps 800 and the bottle body 900 at one time, thereby improving the overall installation efficiency.

[0053] Preferably, the device body 10 includes a first frame 11, a second frame 12, and at least two support members 13, wherein the first frame 11 and the second frame 12 are arranged opposite to each other and spaced apart so that the first frame 11 and the second frame 12 form the operating space 101. Furthermore, the first frame 11 is positioned above the second frame 12. Each support member 13 is installed between the first frame 11 and the second frame 12 to maintain the operating space 101, and each support member 13 is evenly distributed between the first frame 11 and the second frame 12 to divide the operating space 101 and form a channel, thereby allowing the bottle transport channel of the bottle transport member 21 to move within the channel of the operating space 101 for transporting the bottle 900 and the bottle 900 with the cap 800 attached.

[0054] Specifically, the bottle conveying component 21 is mounted on the second frame 12, and the bottle conveying channel of the bottle conveying component 21 is movable within the channel formed by the operating space 101. The transmission guide rail 3131 of the transmission component 313 is mounted on the bottom of the first frame 11. The drive guide rail 2231 of the driving component 223 is mounted on the top of the second frame 12. Specifically, the second frame 12 has a mounting groove at its top for mounting the driving component 223.

[0055] In a modified embodiment, each of the support members 13 is implemented as an automatic lifting bracket, each of the automatic lifting brackets being able to adjust the distance between the first frame 11 and the second frame 12 during lifting, thereby adjusting the distance between the capping assembly 31 mounted on the first frame 11 and the bottle conveying channel of the bottle conveying member 21.

[0056] In other words, when each of the automatic lifting brackets is raised or lowered, the distance between each capping member 312 and the bottle conveying channel of the bottle conveying member 21 can be adjusted. Therefore, when the bottle conveying channel of the bottle conveying member 21 conveys bottles 900 of different heights, each of the automatic lifting brackets is raised or lowered so that each capping member 312 is close to the cap 800 on the bottle 900 of different heights, thereby allowing each capping member 312 to be adjusted to its height position to accommodate the installation of the cap 800 on the bottle 900 of different heights.

The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
