Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, in particular to an in-line capping machine which can be adapted to bottle caps of different sizes. Background Art

[0002] In-line capping machine is a machine that can thread the bottle cap onto the bottle body. It is suitable for automatic capping of bottles in the food, pharmaceutical, daily chemical, pesticide and cosmetic industries.

[0003] The existing in-line capping machine pushes the bottle cap with the cap opening facing downward to the cap conveying space through the bottle cap vibrating disk, and is located at one end of the cap conveying space. When the conveyor belt drives the bottle body to move, the cap opening of the bottle cap at one end of the cap conveying space will fall on the bottle opening of the bottle body. Since the rotating disks are symmetrically arranged on both sides of the conveyor belt in the moving direction of the bottle body, the cap opening of the bottle cap will be threadedly connected to the bottle opening of the bottle body under the rotation of the rotating disk.

[0004] However, in the existing in-line capping machine, since the distance between the rotating disks symmetrically arranged on both sides of the conveyor belt is fixed, the size of the capping space between the symmetrically arranged rotating disks is fixed. When the cap openings of bottle caps of different sizes need to be threadedly connected to the bottle openings of the bottle body, the rotating disks need to be replaced to obtain the expected size of the capping space and achieve the purpose of threading the cap openings of the bottle caps to the bottle openings of the bottle body. Therefore, it is necessary to manufacture a rotating disk with a predetermined size of the capping space to adapt to bottle caps of different sizes, and the process of manufacturing a rotating disk with a predetermined size of the capping space takes extra time and increases the capping cost of the in-line capping machine.

[0027] Refer to the attached figure Figures 1 to 6 According to a preferred embodiment of the utility model, an in-line capping machine that can adapt to bottle caps of different sizes will be described in detail below, wherein the in-line capping machine that can adapt to bottle caps of different sizes includes a device body 10, at least one cap transporting component 20 and at least one capping component 30.

[0028] The device body 10 includes a device body 11 and a conveying assembly 12, wherein the conveying assembly 12 includes a conveyor belt 121, which is disposed on the device body 11 and forms a conveying space 12101 for conveying a bottle 92. The conveyor belt 121 is driven by a conveying driving member to operate.

[0029] The cap transporting assembly 20 is disposed on the device body 10 , and is used to transport a cap body 91 to a predetermined position above the bottle body 92 , and drive the bottle body 92 with the transporting assembly 12 so that a cap opening 911 of the cap body 91 falls to a bottle opening 921 of the bottle body 92 .

[0030] The screw cap assembly 30 is disposed on the device body 11 , and is used to thread the cover opening portion 911 of the cover body 91 of different sizes to the bottle opening portion 921 of the bottle body 92 .

[0031] Specifically, the cap screwing assembly 30 includes a cap screwing mounting frame 31, a plurality of first cap screwing members 32, a second cap screwing member 33 having the same number as the first cap screwing members 32, and at least one cap screwing adjustment member 34. The cap screwing mounting frame 31 is disposed on the device body 11. The first cap screwing member 32 and the second cap screwing member 33 are movably disposed on the cap screwing mounting frame 31 through the cap screwing adjustment member 34. The cap screwing adjustment member 34 is used to adjust the positions of the first cap screwing member 32 and the second cap screwing member 33. The first cap screwing member 32 and the second cap screwing member 33 are arranged in an array on both sides of the direction in which the bottle body 92 drives the cover body 91 to move. The first cap screwing member 32 and the second cap screwing member 33 are used to thread the cover opening portion 911 of the cover body 91 to the bottle opening portion 921 of the bottle body 92.

[0032] The capping adjustment member 34 includes at least one capping positioning rail 341, at least one capping screw 342, at least one capping adjustment driving member 343, at least one first capping adjustment member 344 and at least one second capping adjustment member 345. The capping positioning rail 341 is arranged on the capping mounting frame 31, and the extending direction of the capping positioning rail 341 is arranged to be perpendicular to the moving direction of the bottle body 92. The first capping adjustment member 344 and the second capping adjustment member 345 are arranged on the capping positioning rail 341 so as to be movable along the extending direction of the capping positioning rail 341. The capping adjustment driving member 343 is arranged on the capping mounting frame 31, and the capping screw 342 is rotatably arranged at the output end of the capping adjustment driving member 343, and the extending direction of the capping screw 342 is arranged to be consistent with the extending direction of the capping positioning rail 341. The cap screw 342 is divided into a first cap adjustment part 3421 and a second cap adjustment part 3422. The first cap adjustment part 3421 is connected to the second cap adjustment part 3422, and the surface threads of the first cap adjustment part 3421 and the second cap adjustment part 3422 are opposite. The first cap adjustment member 344 has a first cap adjustment space that matches the surface threads of the first cap adjustment part 3421, and the second cap adjustment member 345 has a second cap adjustment space that matches the surface threads of the second cap adjustment part 3422, so that after the cap screw 342 is set through the first cap adjustment member 344 and the second cap adjustment member 345, the first cap adjustment member 344 and the second cap adjustment member 345 are movably set on the first cap adjustment part 3421 and the second cap adjustment part 3422, respectively.

[0033] The first cover-turning member 32 includes a first rotating disk 321 and a first cover-turning driving member 322, wherein the first rotating disk 321 is rotatably disposed at the output end of the first cover-turning driving member 322. The first cover-turning driving member 322 is disposed at the first cover-turning adjusting member 344 to move following the movement of the first cover-turning adjusting member 344. The second cover-turning member 33 includes a second rotating disk 331 and a second cover-turning driving member 332, wherein the second rotating disk 331 is rotatably disposed at the output end of the second cover-turning driving member 332. The second cover-turning driving member 332 is disposed at the second cover-turning adjusting member 345 to move following the movement of the second cover-turning adjusting member 345. A cover-turning space 301 is formed between the first rotating disk 321 and the second rotating disk 331. The direction in which the first cover-turning driving member 322 drives the first rotating disk 321 to rotate is consistent with the direction in which the second cover-turning driving member 332 drives the second rotating disk 331 to rotate.

[0034] Specifically, the first rotating disk 321 and the second rotating disk 331 are located in the extension direction of the conveyor belt 121 and are located at a height corresponding to the cover body 91 at the bottle mouth 921 of the bottle body 92 .

[0035] It is worth mentioning that when the cover opening portion 911 of the cover body 91 is arranged at the bottle opening portion 921 of the bottle body 92, and the conveyor belt 121 drives the bottle body 92 to move in the extension direction of the conveyor belt 121, and after the cover body 91 enters the screw-capping space 301, the first rotating disk 321 and the second rotating disk 331 will abut against the two sides of the cover body 91, and under the drive of the first screw-capping driving member 322 and the second screw-capping driving member 332, the first rotating disk 321 and the second rotating disk 331 drive the bottle body 92 to rotate, and finally the bottle opening portion 921 of the bottle body 92 is threadedly connected to the cover opening portion 911 of the cover body 91.

[0036] It is understood by those skilled in the art that, since the surface threads of the first cover adjustment part 3421 and the second cover adjustment part 3422 are in opposite directions, when the cover screw rod 342 is driven by the cover adjustment driving member 343 to rotate, the first cover adjustment member 344 and the second cover adjustment member 345 will move toward or in the opposite direction to achieve the purpose of adjusting the size of the cover space 301. In other words, when the size of the cover body 91 changes, there is no need to customize and replace a new cover assembly 30. Only the relative positions of the first cover member 32 and the second cover member 33 need to be adjusted, so that the cover opening portion 911 of the cover body 91 of different sizes can be threadedly connected to the bottle opening portion 921 of the bottle body 92.

[0037] Specifically, the cover conveying assembly 20 includes a cover conveying mounting frame 21, at least one cover conveying belt 22, at least one pair of limiting members 23 and a cover arranging member 26. The cover conveying mounting frame 21 is arranged on the device body 11. The cover conveying belt 22 is arranged on the cover conveying mounting frame 21, and the cover conveying belt 22 forms a cover conveying space 2202 for conveying the cover body 91. One end of the cover conveying belt 22 also forms a cover conveying inlet 2201 connected to the cover conveying space 2202, and the cover conveying inlet 2201 is used to allow the cover body 91 to enter the cover conveying space 2202. The other end of the cover conveying belt 22 also forms a cover dropping space 2203 connected to the cover conveying space 2202, and the cover dropping space 2203 is used to place the cover body 91. The cover dropping space 2203 is located at a predetermined position above the conveyor belt 121.

[0038] At least one pair of limiting members 23 are symmetrically arranged at one end of the cover conveyor belt 22 and close to both sides of the cover falling space 2203. At least one pair of limiting members 23 is used to block the movement of the cover body 91 in the cover falling space 2203 and make a part of the cover opening portion 911 of the cover body 91 located in the cover falling space 2203 suspended at the end of the cover conveyor belt 22.

[0039] The cover aligning component 26 is arranged adjacent to the cover conveying belt 22, and the cover aligning component 26 forms a cover aligning outlet 2601, and the cover aligning outlet 2601 is arranged to be connected to the cover conveying inlet 2201. The cover aligning component 26 is used to adjust the way in which the cover body 91 enters the cover conveying inlet 2201 from the cover aligning outlet 2601, so as to transfer the cover body 91 to the cover conveying space 2202 through the cover conveying inlet 2201 with the cover mouth 911 facing downward through the cover conveying inlet 2201.

[0040] Preferably, the limiting member 23 includes a rebound member 231 and a blocking plate 232, and the blocking plate 232 is movably arranged on the cover conveyor belt 22 through the rebound member 231. The blocking plate 232 is used to prevent the cover body 91 from falling from the cover falling space 2203, so that a part of the cover opening portion 911 of the cover body 91 located in the cover falling space 2203 is suspended at the end of the cover conveyor belt 22, thereby preventing the cover body 91 from falling off the cover conveyor belt 22 due to gravity.

[0041] Those skilled in the art will appreciate that, when the plurality of cover bodies 91 enter the cover transport space 2202 from the cover transport inlet 2201 through the cover arrangement outlet 2601 of the cover arrangement member 26 with the cover opening 911 facing downward, the plurality of cover bodies 91 in the cover transport space 2202 will move from the cover transport space 2202 to the cover falling space 2203 due to mutual squeezing, and a portion of the cover opening 911 of the cover body 91 will be suspended at the end of the cover transport belt 22, and the cover body 91 will no longer move under the obstruction of the blocking plate 232 of the limiting member 23.

[0042] At the same time, driven by the conveyor belt 121, the bottle body 92 moves the bottle mouth portion 921 of the bottle body 92 toward the cover mouth portion 911 of the cover body 91 which is located in the cover falling space 2203 and partially suspended at the end of the cover conveyor belt 22. Driven by the conveyor belt 121, the bottle mouth portion 921 of the bottle body 92 will abut against the suspended position of the cover mouth portion 911 of the cover body 91 and pull the cover body 91 to compress the rebound member 231 by abutting against the blocking plate 232 of the cover body 91, thereby increasing the distance between the blocking plates 232 of a pair of the limiting members 23, and the cover mouth portion 911 of the cover body 91 which partially hangs at the end of the cover conveyor belt 22 will fall on the bottle mouth portion 921 of the bottle body 92.

[0043] Furthermore, after the cover opening portion 911 of the cover body 91 falls on the bottle opening portion 921 of the bottle body 92, the compressed rebound member 231 will rebound to return the blocking plate 232 to its original position, and another cover body 91 will enter the cover falling space 2203 due to the mutual squeezing between the multiple cover bodies 91 in the cover transport space 2202, and a part of the cover opening portion 911 of another cover body 91 will also be suspended at the end of the cover transport belt 22, and will be prevented from falling from the end of the cover transport belt 22 by being blocked by the blocking plate 232 of the limiting member 23, thereby finally achieving the purpose of continuously setting the cover opening portion 911 of the cover body 91 at the bottle opening portion 921 of the bottle body 92.

[0044] It should be noted that when the multiple covers 91 in the cover conveying space 2202 of the cover conveying belt 22 are pressed against each other, there is a risk that the covers 91 may fall off from both sides in the conveying direction of the cover conveying belt 22 .

[0045] Preferably, the cover conveyor assembly 20 further includes at least one pair of protective members 24, at least one pair of the protective members 24 are arranged on the cover conveyor mounting frame 21, at least one pair of the protective members 24 are located on both sides of the extension direction of the cover conveyor belt 22, and at least one pair of the protective members 24 are used to prevent the cover body 91 from falling from both sides of the transmission direction of the cover conveyor belt 22.

[0046] It should be noted that after the cover opening portion 911 of the cover body 91 falls on the bottle opening portion 921 of the bottle body 92, since the contact between the cover opening portion 911 and the bottle opening portion 921 is not tight, when the cover body 91 enters the screw-on space 301 and is driven to rotate by the first rotating disk 321 and the second rotating disk 331, there may be a situation where the cover opening portion 911 of the cover body 91 cannot be threadedly connected to the bottle opening portion 921 of the bottle body 92.

[0047] Preferably, the cover conveying assembly 20 also includes at least one cover pressing member 25, which is arranged at a predetermined position above the cover conveying belt 22 through a connecting rod, and one end of the cover pressing member 25 is located at a predetermined position above the cover falling space 2203, and the cover pressing member 25 is used to press the cover opening portion 911 of the cover body 91 to the bottle opening portion 921 of the bottle body 92 to prevent the cover opening portion 911 of the cover body 91 from being unable to be threadedly connected to the bottle opening portion 921 of the bottle body 92.

[0048] Preferably, in this embodiment, the cover aligning member 26 is implemented to include a vibration plate.

[0049] It should be noted that, in the process that the cover body 91 enters the screw-on cover space 301 and is driven to rotate by the first rotating disk 321 and the second rotating disk 331, the friction between the bottle mouth portion 921 and the cover mouth portion 911 may cause the bottle body 92 to rotate together with the cover body 91, resulting in the cover mouth portion 911 of the cover body 91 being loosened after being threadedly connected to the bottle mouth portion 921 of the bottle body 92.

[0050] Preferably, in one embodiment, the in-line capping machine that can adapt to bottle caps of different sizes also includes a bottle screwing assembly 40, which is arranged on the device body 11, and the bottle screwing assembly 40 is used to prevent the cover mouth part 911 of the cover body 91 from loosening after being threadedly connected to the bottle mouth part 921 of the bottle body 92.

[0051] Specifically, the bottle-spinning assembly 40 includes a bottle-spinning mounting frame 41, a plurality of first bottle-spinning components 42, a second bottle-spinning component 43 having the same number as the first bottle-spinning components 42, and at least one bottle-spinning adjustment component 44. The bottle-spinning mounting frame 41 is disposed on the device body 11. The first bottle-spinning component 42 and the second bottle-spinning component 43 are movably disposed on the bottle-spinning mounting frame 41 through the bottle-spinning adjustment component 44. The bottle-spinning adjustment component 44 is used to adjust the positions of the first bottle-spinning component 42 and the second bottle-spinning component 43. The first bottle-spinning component 42 and the second bottle-spinning component 43 are arranged in an array on both sides of the moving direction of the bottle body 92 and are located at predetermined positions below the first rotating disk 321 and the second rotating disk 331. The first bottle-spinning component 42 and the second bottle-spinning component 43 are used to rotate the bottle body 92 in a direction opposite to the rotation direction of the cover body 91.

[0052] The rotary bottle adjustment member 44 includes at least one rotary bottle positioning rail 441, at least one rotary bottle screw 442, at least one rotary bottle adjustment driving member 443, at least one first rotary bottle adjustment block 444 and at least one second rotary bottle adjustment block 445. The rotary bottle positioning rail 441 is arranged on the rotary bottle mounting frame 41, and the extension direction of the rotary bottle positioning rail 441 is arranged to be perpendicular to the moving direction of the bottle body 92. The first rotary bottle adjustment block 444 and the second rotary bottle adjustment block 445 are arranged on the rotary bottle positioning rail 441 movably along the extension direction of the rotary bottle positioning rail 441. The rotary bottle adjustment driving member 443 is arranged on the rotary bottle mounting frame 41, and the rotary bottle screw 442 is rotatably arranged at the output end of the rotary bottle adjustment driving member 443, and the extension direction of the rotary bottle screw 442 is arranged to be consistent with the extension direction of the rotary bottle positioning rail 441.

The first bottle adjustment part 4421 is connected to the second bottle adjustment part 4422, and the surface threads of the first bottle adjustment part 4421 and the second bottle adjustment part 4422 are opposite. The first bottle adjustment block 444 has a first bottle adjustment space that matches the surface threads of the first bottle adjustment part 4421, and the second bottle adjustment block 445 has a second bottle adjustment space that matches the surface threads of the second bottle adjustment part 4422, so that after the bottle screw 442 is set to pass through the first bottle adjustment block 444 and the second bottle adjustment block 445, the first bottle adjustment block 444 and the second bottle adjustment block 445 are movably set on the first bottle adjustment part 4421 and the second bottle adjustment part 4422, respectively.

[0053] The first bottle rotating member 42 includes a first bottle rotating abutting roller 421 and a first bottle rotating driving member 422, wherein the first bottle rotating abutting roller 421 is rotatably disposed at the output end of the first bottle rotating driving member 422. The first bottle rotating driving member 422 is disposed on the first bottle rotating adjusting block 444 to move following the movement of the first bottle rotating adjusting block 444. The second bottle rotating member 43 includes a second bottle rotating abutting roller 431 and a second bottle rotating driving member 432, wherein the second bottle rotating abutting roller 431 is rotatably disposed at the output end of the second bottle rotating driving member 432. The second bottle rotating driving member 432 is disposed on the second bottle rotating adjusting block 445 to move following the movement of the second bottle rotating adjusting block 445. A bottle rotating space 401 is formed between the first bottle rotating abutting roller 421 and the second bottle rotating abutting roller 431. The direction in which the first bottle rotating driving member 422 drives the first bottle rotating abutting roller 421 to rotate is consistent with the direction in which the second bottle rotating driving member 432 drives the second bottle rotating abutting roller 431 to rotate, and is opposite to the direction in which the first rotating disk 321 rotates.

[0054] Preferably, the first rotating bottle abutting roller 421 and the second rotating bottle abutting roller 431 are located at a corresponding height of the bottle body 92 .

[0055] It is worth mentioning that when the conveyor belt 121 drives the bottle body 92 to move in the extension direction of the conveyor belt 121 and makes the bottle body 92 enter the bottle spinning space 401, the first bottle spinning abutment roller 421 and the second bottle spinning abutment roller 431 will abut against the two sides of the bottle body 92. Driven by the first bottle spinning driving member 422 and the second bottle spinning driving member 432, the first bottle spinning abutment roller 421 and the second bottle spinning abutment roller 431 drive the bottle body 92 to rotate in the direction opposite to the rotation direction of the cover body 91, thereby preventing the bottle body 92 from rotating together with the cover body 91, and finally ensuring that the cover mouth part 911 of the cover body 91 is threadedly connected to the bottle mouth part 921 of the bottle body 92 and will not loosen.

[0056] Those skilled in the art can understand that, since the surface threads of the first bottle rotating adjustment part 4421 and the second bottle rotating adjustment part 4422 are in opposite directions, when the bottle rotating screw 442 is driven by the bottle rotating adjustment driving member 443 to rotate, the first bottle rotating adjustment block 444 and the second bottle rotating adjustment block 445 will move toward or in the opposite direction to achieve the purpose of adjusting the size of the bottle rotating space 401. In other words, when the size of the bottle body 92 changes, there is no need to customize and replace a new bottle rotating assembly 40, and only the relative positions of the first bottle rotating member 42 and the second bottle rotating member 43 need to be adjusted to achieve the purpose of rotating the bottle body 92 of different sizes.

[0057] It should be noted that the in-line capping machine that can adapt to bottle caps of different sizes will generate vibrations during operation, which may cause the bottles 92 in the conveying space 12101 of the conveyor belt 121 to fall due to the vibrations.

[0058] Preferably, the conveying assembly 12 further includes at least one pair of blocking members 122 , wherein the pair of blocking members 122 are arranged on both sides of the conveying direction of the conveyor belt 121 , and the pair of blocking members 122 are used to prevent the bottle body 92 from falling from the conveying space 12101 .

[0059] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
