Description

Technical Field

[0001] The utility model relates to the field of filling equipment, in particular to a capping device applicable to caps of different sizes. Background Art

[0002] Capping is an important part of the liquid filling process. At present, during capping, the bottle body is conveyed by a conveyor belt. During the conveying process, the cap is sent to directly above the bottle body by a cap feeding assembly, and the cap is driven by the top of the bottle body to cover the bottle mouth. Then the conveyor belt continues to convey and passes through a capping member, and the capping member located on both sides of the conveyor belt screws the cap tightly onto the bottle body.

[0003] In the prior art, since the size of the channel for the cap feeding assembly to convey the cap is fixed, and the sizes of the caps to be conveyed are sometimes different, when conveying caps of different sizes, workers need to replace the cap feeding assembly to adapt to caps of different sizes. Similarly, since the positions of the capping parts of the capping member are fixed, that is, the distance between the capping parts on both sides of the cap cannot be changed, when screwing caps of different sizes, workers need to replace the capping member to adapt to caps of different sizes, which is too troublesome.

[0004] In addition, some capping devices will add a bottle rotating member in addition to rotating the cap. The bottle rotating member drives the bottle body to rotate from both sides of the bottle body to perform rotation in the direction opposite to the rotation direction of the cap, so as to screw the cap and the bottle body together more quickly and tightly. Since the positions of the bottle rotating parts of the bottle rotating member are fixed, that is, the distance between the bottle rotating parts arranged on both sides of the bottle body cannot be changed, workers need to replace the bottle rotating member to adapt to bottle bodies of different sizes when rotating caps of different sizes.

The basic principles defined in the following description of the present utility model can be applied to other implementation manners, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present utility model.

[0027] It can be understood that the term "one" 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 other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0028] Reference Figures 1 to 6 , the cap screwing device applicable to caps of different sizes according to a preferred embodiment of the present utility model will be elaborated in detail below. The cap screwing device applicable to caps of different sizes is used to screw the cap 80 onto the bottle body 90. The cap screwing device applicable to caps of different sizes includes a cap feeding assembly 10, a conveying assembly 20, a screwing assembly 30, and a device main body 40.

[0029] As Figures 1 to 3 shown, the cap feeding assembly 10 includes a cap feeding member 11 and a cap stopping member 12. The bottle cap 80 can be fed by the cap feeding member 11 above the bottle body 90. The cap feeding member 11 includes a cap feeding main body 111 and at least one first adjusting member 112. The cap feeding main body 111 includes a cap feeding part 1111 and two cap blocking parts 1112. The two cap blocking parts 1112 are symmetrically and movably installed on both sides of the cap feeding part 1111. And with the cap blocking parts 1112 as the sides and the cap feeding part 1111 as the bottom surface, a cap feeding channel 11101 with an inlet and an outlet is formed. The first adjusting member 112 is installed on the cap blocking part 1112 in a manner that can adjust the distance between the two cap blocking parts 1112, so as to change the width of the cap feeding channel 11101, and finally adapt to bottle caps 80 of different sizes.

[0030] The cap feeding part 1111 is inclinedly arranged with the outlet lower than the inlet. The cap stopping member 12 is arranged at one end of the cap feeding channel 11101 where the outlet is formed. And the cap stopping member 12 is arranged to be able to intercept the bottle cap 80, so that when the bottle cap 80 reaches the outlet along the cap feeding channel 11101 with its cap opening facing downwards, the bottle cap 80 is intercepted by the cap stopping member 12 at the outlet of the cap feeding part 1111 in a manner that its cap opening part is suspended.

[0031] Preferably, the first adjusting member 112 is implemented as a cylinder, and the number of the first adjusting members 112 is implemented as two. Each first adjusting member 112 is installed on one cap blocking part 1112, and the two first adjusting members 112 are arranged to drive the two cap blocking parts 1112 to move in opposite directions, so that the distance between the two cap blocking parts 1112 changes, thereby changing the width of the cap feeding channel 11101.

[0032] Similarly preferably, the first adjustment member 112 includes a first driving member 1121, at least a pair of first sliders 1122, a first screw 1123, and a first slide rail 1124, wherein the first driving member 1121 is implemented as a driving motor. Each of the first sliders 1122 is fixed to one of the cover members 1112, and the two first sliders 1122 are slidably mounted on the first slide rail 1124, and the first slide rail 1124 is fixed to the conveying member 21 or the device main body 40. The thread direction on the first screw 1123 is provided with two opposite parts, and the two first sliders 1122 are symmetrically threadedly connected to the two parts with opposite thread directions on the first screw 1123. The first slide rail 1124 is parallel to the first screw 1123, and the first driving member 1121 is drivingly connected to the first screw 1123, so that the first driving member 1121 can drive the first screw 1123 to rotate, thereby driving the two first sliders 1122 to move in opposite directions and synchronously along the first slide rail 1124, and further adjusting the distance between the two cover members 1112.

[0033] Those skilled in the art can understand that when the first driving member 1121 drives the first screw 1123 to rotate, the first slider 1122 cannot rotate because it is mounted on the first slide rail 1124. Therefore, the first slider 1122 slides on the first slide rail 1124 under the influence of the thread. Also, because the two first sliders 1122 are symmetrically threadedly connected to the two parts with opposite thread directions on the first screw 1123, the two first sliders 1122 move in opposite directions, thereby driving the two cover members 1112 to move in opposite directions and synchronously, and further adjusting the width of the cap feeding channel 11101, and finally adapting to caps 80 of different sizes.

[0034] As Figure 1 As shown, the conveying assembly 20 is mounted on the device main body 40. The conveying assembly 20 includes a conveying member 21, and the conveying member 21 is arranged directly below the cap feeding member 1111 and is used for conveying the bottle body 90. The distance between the bottom end of the cap 80 at the outlet of the cap feeding channel 11101 and the upper surface of the conveying member 21 is less than the height of the bottle body 90, so that when the bottle body 90 is conveyed through the outlet of the cap feeding channel 11101, the cap 80 can be hooked on the top end of the bottle body 90 and can be driven by the bottle body 90 to be taken out of the cap feeding channel 11101 for subsequent screwing operation.

[0035] By way of example, the conveying member 21 is implemented as a conveyor belt.

[0036] As Figure 4As shown, the tightening assembly 30 is located in the conveying direction of the bottle body 90 that moves under the cap delivery body 111 and is conveyed by the conveying assembly 20 , and the tightening assembly 30 can tighten the bottle cap 80 to the bottle body 90 .

[0037] Those skilled in the art can understand that, the bottle cap 80 is delivered to the exit of the cap delivery channel 11101 by the cap delivery member 1111, the bottle body 90 is delivered by the conveying member 21 and when it is close to the bottle cap 80, the bottle cap 80 is pulled away from the cap delivery channel 11101, so that the bottle cap 80 is covered on the bottle body 90; thereafter, the conveying member 21 continues to deliver the bottle body 90 and when the bottle body 90 passes through the tightening assembly 30, the tightening assembly 30 drives the bottle cap 80 to rotate, so that the bottle cap 80 is tightened on the bottle body 90.

[0038] Preferably, the cover stopping member 12 comprises at least one baffle plate 121 and at least one elastic member 122, wherein one end of each elastic member 122 is connected to the baffle plate 121, and the other end is connected to the cover blocking member 1112 to form the side wall of the cover delivery channel 11101. The distance between one end of the baffle plate 121 relatively close to the outlet of the cover delivery channel 11101 and the corresponding cover blocking member 1112 is greater than the distance between the other end and the corresponding cover blocking member 1112, and the end of the baffle plate 121 relatively close to the outlet of the cover delivery channel 11101 can approach or move away from the cover blocking member 1112. At the same time, when the bottle cap 80 contacts the baffle 121, the baffle 121 is acted upon by the force of the elastic member 122 and the bottle cap 80, so that the edge portion of the bottle cap 80 is kept suspended at the exit of the cap delivery channel 11101, so that the bottle cap 80 can be contacted by the bottle body 90 and pulled away from the cap delivery channel 11101, and the elastic member 122 can reset the baffle 121 after the bottle cap 80 moves away from the cap delivery channel 11101 to intercept the next bottle cap 80.

[0039] As an example, the elastic member 122 is implemented as a torsion spring.

[0040] It can be understood that when the bottle cap 80 is pulled by the bottle body 90, the baffle 121 is subjected to an increased force from the bottle cap 80, thereby squeezing the elastic member 122, and then the bottle cap 80 breaks through the obstruction of the baffle 121 and covers the bottle body 90; and when the baffle 121 is no longer subjected to the pressure from the bottle cap 80, the elastic member 122 recovers to push the baffle 121 to reset, thereby blocking the next bottle cap 80 at the exit of the cap delivery channel 11101.

[0041] Preferably, if Figure 1As shown, the cap feeding assembly 10 further includes a cap loading member 13. The cap loading member 13 is connected to the cap feeding member 1111 and the cap loading member 13 communicates with the inlet of the cap feeding channel 11101. The cap loading member 13 can orderly push a plurality of the caps 80 to the inlet of the cap feeding channel 11101 with the cap openings facing downwards, so that the caps 80 are sent by the cap feeding member 1111 to the outlet of the cap feeding channel 11101.

[0042] As an example, the cap loading member 13 is implemented as a cap vibrating disk.

[0043] Preferably, as Figure 2 shown, the cap feeding assembly 10 further includes a cap pressing member 14. The cap pressing member 14 is installed above the outlet of the cap feeding channel 11101, and the distance between the cap pressing member 14 and the cap feeding member 1111 is equal to the height of the cap 80. When the cap 80 is intercepted by the cap stopping member 12 in a partially suspended manner, the cap pressing member 14 limits the part of the cap 80 suspended at the outlet of the cap feeding channel 11101 in the cap feeding channel 11101, preventing the cap 80 from rolling out of the cap feeding channel 11101 due to the subsequent extrusion of the cap 80.

[0044] It is worth mentioning that since the cap 80 needs to be hooked on the top of the bottle body 90 and be taken away from the cap feeding channel 11101 by the bottle body 90, the whole cap 80 is inclined and partially suspended. However, after the cap 80 is taken away from the cap feeding channel 11101, the cap 80 may still remain inclined and cover above the bottle body 90.

[0045] More preferably, the cap pressing member 14 horizontally extends in the moving direction towards the bottle body 90 to form a flattening portion 141. The height difference between the flattening portion 141 and the conveying member 21 is less than the height difference between the highest end of the cap 80 when the cap 80 is skewed and covers the bottle body 90 and the conveying member 21, and the height difference between the flattening portion 141 and the conveying member 21 is greater than the height difference between the upper surface of the cap 80 and the conveying member 21 when the cap 80 stably covers the bottle body 90.

[0046] It can be understood that during the process that the cap 80 is pulled away from the cap feeding channel 11101 by the bottle body 90 and covers the mouth of the bottle body 90, the top end of the cap 80 is always pressed by the flattening portion 141 of the cap pressing member 14, so that the cap 80 stably covers the mouth of the bottle body 90, preventing the cap 80 on the bottle body 90 from being skewed and being difficult to be tightened by the tightening assembly 30.

[0047] Preferably, the conveying assembly 20 further includes at least a pair of bottle blocking members 22. At least a pair of the bottle blocking members 22 are symmetrically installed on both sides of the conveyor 21, and a conveying channel 201 is formed with the bottle blocking members 22 as the sides and the conveyor 21 as the bottom surface for conveying the bottle body 90, so as to prevent the bottle body 90 from collapsing or tilting during conveying.

[0048] As an example, the bottle blocking member 22 is implemented as a railing.

[0049] Preferably, the screwing assembly 30 includes a capping mechanism 31. The capping mechanism 31 includes at least a pair of capping members 311. Each pair of the capping members 311 are installed on both sides of the bottle cap 80 on the bottle body 90 on the conveyor 21 with adjustable positions and are configured to drive the bottle cap 80 to rotate, so as to complete the liquid filling.

[0050] Specifically, each capping member 311 includes a capping part 3111 and a capping driving part 3112. The capping part 3111 is drivably installed on the capping driving part 3112, and all the capping parts 3111 are configured to rotate in the same direction. Two opposite capping parts 3111 are symmetrically arranged above the conveyor 21 with respect to the bottle cap 80 on the bottle body 90, and the bottle body 90 first passes through the cap feeding part 1111 and then passes through the two capping parts 3111. The height difference between the bottom end of the capping part 3111 and the conveyor 21 is less than the height difference between the top end of the bottle cap 80 on the bottle body 90 and the conveyor 21, and the height difference between the top end of the capping part 3111 and the conveyor 21 is greater than the height difference between the bottom end of the bottle cap 80 on the bottle body 90 and the conveyor 21, so that when the bottle body 90 with the bottle cap 80 covering the bottle mouth passes between at least a pair of capping parts 3111, the capping parts 3111 screw the bottle cap 80 tightly onto the bottle body 90.

[0051] As an example, the capping part 3111 is implemented as a rotating wheel. The capping driving part 3112 is implemented as a driving motor.

[0052] Preferably, the capping mechanism 31 further includes at least a second adjusting member 312. The second adjusting member 312 is installed on the capping member 311 in a manner that can adjust the distance between the capping part 3111 and the bottle cap 80 at the top of the bottle body 90 that is conveyed by the conveyor 21 and moves to the outside of the capping part 3111.

[0053] Preferably, the second adjustment member 312 is implemented as a cylinder, and the number of the second adjustment members 312 is implemented corresponding to the number of the capping members 3111. Each of the second adjustment members 312 is mounted on one of the capping members 311, and two opposite second adjustment members 312 can drive two opposite capping members 3211 to move in opposite directions, so that the distance between the two capping members 3111 is changed by the second adjustment member 312, thereby adapting to bottle caps 80 of different sizes.

[0054] Also preferably, the second adjustment member 312 includes at least one second driving member 3121, at least a pair of second sliding blocks 3122, a second screw rod 3123 and a second slide rail 3124, wherein the second driving member 3121 is implemented as a driving motor. Each of the second sliding blocks 3122 is fixed to one of the capping driving members 3112, and the two second sliding blocks 3122 are slidably mounted on the second slide rail 3124, and the second slide rail 3124 is mounted on the device main body 40.

[0055] The thread direction on the second screw rod 3123 is provided with two opposite parts, and the two second sliding blocks 3122 are symmetrically threadedly connected to the two parts with opposite thread directions on the second screw rod 3123. The second slide rail 3124 is parallel to the second screw rod 3123, and the second driving member 3121 is drivingly connected to the second screw rod 3123, so that the second driving member 3121 can drive the second screw rod 3123 to rotate, thereby driving the two second sliding blocks 3122 to move in opposite directions and synchronously along the second slide rail 3124, and further adjusting the distance between the two capping members 3111.

[0056] Those skilled in the art can understand that when the second driving member 3121 drives the second screw rod 3123 to rotate, the second sliding block 3122 cannot rotate because it is mounted on the second slide rail 3232. Therefore, the second sliding block 3122 slides on the second slide rail 3232 under the influence of the thread. Also, because the two second sliding blocks 3122 are symmetrically threadedly connected to the two parts with opposite thread directions on the second screw rod 3123, the two second sliding blocks 3122 move in opposite directions, thereby driving the two capping driving members 3112 to move in opposite directions and synchronously, and further adjusting the distance between the two capping members 3111, and finally adapting to bottle caps 80 of different sizes.

[0057] Preferably, as Figure 5As shown, the tightening assembly 30 further includes a bottle rotating mechanism 32. The bottle rotating mechanism 32 includes at least a pair of bottle rotating members 321. Each pair of the bottle rotating members 321 is adjustably mounted on both sides of the bottle body 90 on the conveying member 21 and is configured to drive the bottle body 90 to rotate in a direction opposite to the rotation direction of the bottle cap 80, so as to accelerate the capping process and screw the bottle cap 80 more tightly onto the bottle body 90.

[0058] Each of the bottle rotating members 321 includes a bottle rotating part 3211 and a bottle rotating driving part 3212. The bottle rotating part 3211 is drivably mounted on the bottle rotating driving part 3212. All the bottle rotating parts 3211 are configured to rotate in the same direction, and the rotation direction of the bottle rotating part 3211 is opposite to the rotation direction of the capping part 3111. The height difference between the two bottle rotating parts 3211 and the conveying member 21 is less than the height of the bottle body 90, so that when the bottle body 90 with the bottle cap 80 on its mouth passes between the two opposite bottle rotating parts 3211, the bottle rotating parts 3211 drive the bottle body 90 to rotate in a direction opposite to the rotation direction of the bottle cap 80.

[0059] Preferably, the bottle rotating mechanism 32 further includes at least one third adjusting member 322. The third adjusting member 322 is mounted on the bottle rotating member 321 in a manner capable of adjusting the distance between the bottle rotating part 3211 and the bottle body 90 conveyed by the conveying member 21 and moved to the outside of the capping part 3111.

[0060] Preferably, the third adjusting member 322 is implemented as a cylinder, and the number of the third adjusting members 322 is implemented to be the same as the number of the bottle rotating parts 3211. Each of the third adjusting members 322 is mounted on one of the bottle rotating parts 3211, and the two opposite third adjusting members 322 can drive the two opposite bottle rotating parts 3211 to move in opposite directions, so that the distance between the two opposite bottle rotating parts 3211 is changed, thereby adapting to bottle bodies 90 of different sizes.

[0061] Also preferably, the third adjusting member 322 includes at least one third driving part 3221, at least a pair of third sliding blocks 3222, a third screw rod 3223 and a third slide rail 3224, wherein the third driving part 3221 is implemented as a driving motor. Each of the third sliding blocks 3222 is fixed to one of the bottle rotating driving parts 3212, and the two third sliding blocks 3222 are slidably mounted on the third slide rail 3224, and the third slide rail 3224 is mounted on the equipment main body 40.

[0062] The thread direction on the third screw 3223 is provided with two opposite parts, and the two third sliders 3222 are symmetrically threadedly connected to the two parts with opposite thread directions on the third screw 3223. The third slide rail 3224 is parallel to the third screw 3223, and the third driving member 3221 is drivably connected to the third screw 3223, so that the third driving member 3221 can drive the third screw 3223 to rotate, thereby driving the two third sliders 3222 to move in opposite directions and synchronously along the third slide rail 3224, and further enabling the two bottle rotating members 3211 to move away from or close to each other.

[0063] Those skilled in the art can understand that when the third driving member 3221 drives the third screw 3223 to rotate, the third slider 3222 cannot rotate because it is installed on the third slide rail 3224. Therefore, the third slider 3222 slides on the third slide rail 3224 under the influence of the thread. Also, because the two third sliders 3222 are symmetrically threadedly connected to the two parts with opposite thread directions on the third screw 3223, the two third sliders 3222 move in opposite directions, thereby driving the bottle rotating driving member 3212 to move in opposite directions and synchronously, and further adjusting the distance between the two relatively arranged bottle rotating members 321, and finally adapting to the bottles 90 of different sizes.

[0064] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the 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 shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
