[0068] First of all, the application scenario of the present disclosure is introduced here.
As illustrated in in Fig. 1, in a conventional cap body 1, a bottom of the cap body 1 is provided with a groove so that the cap body 1 is usually grabbed in a snap-fitted manner during a capping operation; as a comparison, a new-type cap body 1 includes a pouring opening and a cap 11, and a bottom of the pouring opening is provided with a complete film 12, as illustrated in Figs. 2 and 3. The grabbing and conveying mode for the existing cap body 1 cannot meet the usage requirements of the special structure of the new-type cap body 1.
[0069] Based on the above-described application scenario, embodiments of the application provide a capping device and a capping method.
[0070] The technical solutions of the embodiments of the present disclosure will be described below in a clear and complete way in connection with the drawings related to the embodiments of the present disclosure. Apparently, the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the described embodiments herein, those ordinary skilled in the art can obtain all other embodiment(s), without any inventive work, which should be within the scope of protection of the present disclosure.
[0071] As illustrated in Figs. 4 to 9, an embodiment of the present disclosure provides a capping device, including a cap-guiding mechanism 100, a cap-pushing mechanism 200 and a cap-sucking mechanism 300; the cap-guiding mechanism 100 is provided with a cap-feeding inlet 101 and a cap-pushing channel 102 cooperated with the cap-pushing mechanism 200; the cap-sucking mechanism 300 has a sucking position and a capping position with corresponding to the cap-guiding mechanism 100; and when the cap-sucking mechanism 300 is at the sucking position, the cap-pushing mechanism 200 penetrates through the cap-pushing channel 102 and pushes the cap body 1 that enters the cap-pushing channel 102 through the cap-feeding inlet 101 to a suction end 301 of the cap-sucking mechanism 300; the suction end 301 is used for sucking and conveying the cap body 1.
[0072] The above-described cap-sucking mechanism 300 of the capping device can suck and convey a cap body 1 provided with a film 12, so as to complete the capping operation for the new-type cap body 1. Specifically, the cap body 1 can enter the inside of the cap-pushing channel 102 through the cap-feeding inlet 101 of the cap-guiding mechanism 100; at this time, the cap-sucking mechanism 300 is at the sucking position, and the cap body 1 is located between the cap-sucking mechanism 300 and the cap-pushing mechanism 200; the cap-pushing mechanism 200 enters the cap-pushing channel 102 to push the cap body 1 to the suction end 301 of the cap-sucking mechanism 300; after sucked by the suction end 301 of the cap-sucking mechanism 300, the cap body 1 can be conveyed to the capping position to complete the capping operation. Thus, it can be seen that the capping device provided by the present embodiment can be well adapted to the new-type cap body 1, and can suck and convey the new-type cap body 1 stably at a high speed.
[0073] It should be noted that the capping operation is usually to weld the cap body 1 onto a sleeve 2, for example, an ultrasonic welding method is adopted to heat a joint where the cap body 1 and the sleeve 2 are connected to a molten state so that they can be attached onto each other. Therefore, the capping device further includes a welding mechanism 400, and the welding mechanism 400 and the cap-sucking mechanism 300 sandwich the cap body 1 and the sleeve 2 therebetween so that the cap body 1 and the sleeve 2 are hermetically connected.
[0074] The above-mentioned capping process of the capping device is described below. [0075] As illustrated in Fig. 4, the cap-sucking mechanism 300 is at the sucking position, and the cap body 1 enters the cap-pushing channel 102 through the cap-feeding inlet 101 of the cap-guiding mechanism 100 along the direction A indicated in Fig. 4. When completely falling into the cap-pushing channel 102, the cap body 1 is located between the capsucking mechanism 300 and the cap-pushing mechanism 200, as illustrated in Fig. 5, the cappushing mechanism 200 moves towards the cap body 1 along the direction B indicated in Fig. 5 to push the cap body 1 to the suction end 301 of the cap-sucking mechanism 300. As illustrated in Fig. 6, after the cap-sucking mechanism 300 sucks the cap body 1, it drives the cap body 1 to be inserted into the sleeve 2 along the direction C indicated in Fig. 6. An inner side wall of the sleeve 2 is provided with a through hole adapted to the cap body 1 , as illustrated in Fig. 7, the cap-sucking mechanism 300 drives the cap body 1 to move towards the through hole along the direction D indicated in Fig. 7 so that the cap body 1 penetrates through the through hole. At this time, the cap-sucking mechanism 300 is at the capping position, and the welding mechanism 400 welds the sleeve 2 and the cap body 1 with the cooperation of the capsucking mechanism 300 to complete the capping operation. After the capping operation is completed, as illustrated in Fig. 8, the cap-sucking mechanism 300 needs to be switched from the capping position to the sucking position for a next operation. Fig. 8 illustrates an action path along which the cap-sucking mechanism 300 is switched from the capping position to the sucking position, i.e., moving away from the welding mechanism 400 in the direction E firstly, and then moving in the direction F until returning to the capping position.
[0076] In a possible implementation, as illustrated in Fig. 9, a hard suction chuck is adopted as the suction end 301 to suck the cap body 1. In order to show the specific structure inside the cap-pushing channel 102, the cap-guiding mechanism 100 is sectioned in Fig. 9; in combination with Fig. 4, when in use, the cap-feeding inlet 101 is located above the cappushing channel 102, and the cap body 1 can fall into the cap-pushing channel 102 under the action of its own gravity. The cap-pushing mechanism 200 can push the cap body 1 towards the suction end until the cap body 1 is sucked onto the cap-sucking mechanism 300 as illustrated in Fig. 10.
[0077] In some embodiments, the cap-sucking mechanism 300 includes a suction anvil 310 provided with a suction part 320 for sucking the cap body 1; an air suction channel 311 is provided inside the suction anvil 310, and a surface of the suction part 320 at a side facing away from the suction anvil 310 is a suction surface 321, and the suction surface 321 is provided with a plurality of suction holes communicated with the air suction channel 311.
[0078] In a possible implementation, as illustrated in Fig. 11, the cap-sucking mechanism 300 includes a suction anvil 310 provided with a suction part 320; that is to say, the suction part 320 and the suction anvil 310 are formed integrally. A surface of the suction part 320 at a side facing away from the suction anvil 310 is a suction surface 321 provided with a plurality of suction holes. As illustrated in Fig. 12, an air suction channel 311 is provided inside the suction anvil 310 and is communicated with the suction holes in the suction surface 321. When the cap body 1 is in contact with the suction surface 321, the air between the suction surface 321 and the cap body 1 is sucked away through the suction holes by means of the air suction channel 311, so that the cap body 1 is sucked onto the suction surface 321.
[0079] In some embodiments, the suction surface 321 is provided with a central suction hole 322, a first suction hole group and a second suction hole group; the first suction hole group includes a plurality of first suction holes 323 annularly arranged around the central suction hole 322, and the second suction hole group includes a plurality of second suction holes 324 annularly arranged around the central suction hole 322; and the second suction hole group is located at an outer side of the first suction hole group.
[0080] In a possible implementation, as illustrated in Fig. 13, the suction holes in the suction surface 321 are arranged annularly, so that the cap body 1 is uniformly stressed. In combination with Fig. 1, because the film 12 of the cap body 1 is in a circular shape, the suction holes in the suction surface 321 are also arranged in the shape of a circular ring. Referring to Fig. 13, the suction surface 321 is provided with a central suction hole 322, a first suction hole group and a second suction hole group, wherein the central suction hole 322 is located at the center of the suction surface 321, the first suction hole group surrounds an outer side of the central suction hole 322, and the second suction hole group surrounds an outer side of the first suction hole group. The first suction hole group includes a plurality of first suction holes 323, and the plurality of first suction holes 323 are annularly arranged at intervals. By way of example, as illustrated in Fig. 13, there are four first suction holes 323. The second suction hole group includes a plurality of second suction holes 324, and the plurality of second suction holes 324 are annularly arranged at intervals. By way of example, as illustrated in Fig. 13, there are four second suction holes 324.
[0081] It should be noted that in order to ensure a suction strength at an edge of the cap body 1, a diameter of the second suction hole 324 is greater than that of the first suction hole
323. By way of example, the diameter of the first suction hole 323 is 3 mm and the diameter of the second suction hole 324 is 4 mm.
[0082] It should be understood that the film 12 of the cap body 1 may be out of flatness due to the existence of the pouring opening and a plastic deformation of the material. In order to ensure a suction stability, the first suction hole group and the second suction hole group correspond to the relatively flat areas on the plane of the film 12 at the bottom of the cap body 1, respectively. By way of example, a radius of a circle where the first suction hole 323 in the first suction hole group is located is smaller than a radius of the pouring opening of the cap body 1, and a radius of a circle where the second suction hole 324 in the second suction hole group is located is greater than the radius of the pouring opening of the cap body 1. Specifically, the radius of the circle where the first suction hole 323 in the first suction hole group is located may be 6 mm, and the radius of the circle where the second suction hole 324 in the second suction hole group is located may be 15 mm.
[0083] In order to prevent the equipment from being damaged by the cap body 1 due to misoperation such as misplacing the cap body 1, in some embodiments, the suction part 320 is provided with a vacuum breaking hole 325.
[0084] In a possible implementation, as illustrated in Figs. 11 and 12, the suction part 320 includes an annular side surface surrounding the suction surface 321, and the annular side surface is provided with a vacuum breaking hole 325; at the same time, the suction surface 321 is provided with an air vent 326 communicated with the vacuum breaking hole 325 to break the vacuum. It should be understood that there can be one or more vacuum breaking holes 325 and also one or more air vents 326. When there is one air vent 326, all the vacuum breaking holes 325 are communicated with this one air vent 326. When there is a plurality of air vents 326, the number of the air vents 326 can be as same as the number of the vacuum breaking holes 325, and one of the air vents 326 can be communicated with one of the vacuum breaking holes 325. Of course, the number of the air vents 326 can also be different from the number of the vacuum breaking holes 325; that is, it’s possible for one of the air vents 326 to be communicated with a plurality of vacuum breaking holes 325, or it’s possible for a plurality of air vents 326 to be communicated with one of the vacuum breaking holes 325.
[0085] In a possible implementation, as illustrated in Fig. 13, the suction surface 321 is provided with four air vents 326, and the four air vents 326 are annularly arranged around the central suction hole 322 at intervals. Furthermore, these four air vents 326 surround an outer side of the first suction hole group, and the second suction hole group surrounds an outer side of the four air vents 326. By way of example, a radius of a circle where the four air vents 326 are located may be 9 mm, and a diameter of the air vent 326 may be 6 mm.
[0086] In some embodiments, the suction surface 321 is provided with a positioning convex ring 327 for cooperating with a flange in the cap body 1 so as to position the cap body 1; when the cap body 1 is sucked onto the cap-sucking mechanism 300, an inner side surface of the positioning convex ring 327 is in contact with an outer side surface of the flange in the cap body 1, and a height of the positioning convex ring 327 is not greater than a thickness of the flange in the cap body 1. [0087] In a possible implementation, referring to Fig. 10 in conjunction with Fig. 11, the suction surface 321 is provided with a positioning convex ring 327. When the cap body 1 is sucked onto the cap-sucking mechanism 300, an inner side surface of the positioning convex ring 327 is in contact with an outer side surface of the flange in the cap body 1 so as to limit a position of the cap body 1. In order to prevent the positioning convex ring 327 from affecting the contact between the cap body 1 and the sleeve 2 during the capping operation, a height of the positioning convex ring 327 is not greater than a thickness of the flange in the cap body 1, that is, the height of the positioning convex ring 327 may be equal to the thickness of the flange in the cap body 1 (i.e., the film 12) or the height of the positioning convex ring 327 may be smaller than the thickness of the flange in the cap body 1 (i.e., the film 12).
[0088] In some embodiments, the positioning convex ring 327 is provided with a first notch 327a through which the suction surface 321 is exposed.
[0089] It should be noted that if a sensor detects a distance between the suction surface 321 and the sleeve 2 during the capping operation, the positioning convex ring 327 may affect the function realization of the sensor, so it is necessary to arrange a first notch 327a on the positioning convex ring 327 to expose the suction surface 321. In a possible implementation, referring to Fig. 11 in conjunction with Fig. 13, the positioning convex ring 327 is provided with two first notches 327a; of course, there may also be one first notch 327a, and the arrangement position of the first notch 327a is mainly adapted to the position of the sensor. As illustrated in Fig. 13, due to the existence of two first notches 327a, the positioning convex ring 327 is divided into two arc-shaped convex rings, and the positioning of the cap body 1 can also be realized.
[0090] In a possible implementation, what is different from the structure in Fig. 9 is that, a soft suction chuck is adopted as the suction end 301 of the cap-sucking mechanism 300 to suck the cap body 1. As illustrated in Fig. 14, in order to show the specific structure inside the cap-pushing channel 102, the cap-guiding mechanism 100 is sectioned in Fig. 14. In combination with Fig. 4, when in use, the cap-feeding inlet 101 is located above the cappushing channel 102, and the cap body 1 can fall into the cap-pushing channel 102 under the action of its own gravity. The cap-pushing mechanism 200 can push the cap body 1 towards the suction end until the cap body 1 is sucked onto the cap-sucking mechanism 300. [0091] In some embodiments, the cap-sucking mechanism 300 includes a suction anvil 310 and a flexible suction chuck 340; the suction anvil 310 is provided with a mounting seat 330, and the mounting seat 330 is provided with a concave part 331; an air suction channel 311 communicated with the concave part 331 is provided inside the suction anvil 310; the flexible suction chuck 340 is mounted on a bottom wall of the concave part 331 and is communicated with the air suction channel 311.
[0092] In a possible implementation, as illustrated in Fig. 15, the cap-sucking mechanism 300 includes a suction anvil 310 and a flexible suction chuck 340, and the suction anvil 310 is provided with a mounting seat 330 which can be integrally formed with the suction anvil 310. The mounting seat 330 is provided with a concave part 331 ; as illustrated in Fig. 16, an air suction channel 311 is provided inside the suction anvil 310; a bottom wall of the concave part 331 is provided with a mounting hole communicated with the air suction channel 311, and the flexible suction chuck 340 is mounted on the bottom wall of the concave part 331 through the mounting hole. By way of example, referring to Fig. 15, an end of the flexible suction chuck 340 facing away from the cap body 1 is provided with a threaded j oint, and the flexible suction chuck 340 is mounted in the concave part 331 through the threaded j oint.
[0093] In some embodiments, a side wall of the mounting seat 330 is provided with an avoidance slot 332 communicated with the concave part 331 for mounting the flexible suction chuck 340.
[0094] It should be noted that, with reference to Figs. 15-17, in order to screw or unscrew the flexible suction chuck 340 conveniently, a side wall of the mounting seat 330 is provided with an avoidance slot 332 communicated with the concave part 331 to avoid a mounting tool of the flexible suction chuck 340, such as a wrench. As illustrated in Fig. 17, the side wall of the mounting seat 330 is provided with three avoidance slots 332.
[0095] In some embodiments a surface of the mounting seat 33 at a side facing away from the suction anvil 310 is provided with a positioning convex ring 333 for cooperating with a flange in the cap body 1 so as to position the cap body 1; when the cap body 1 is sucked onto the cap-sucking mechanism 300, an inner side surface of the positioning convex ring 333 is in contact with an outer side surface of the flange in the cap body 1, and a height of the positioning convex ring 333 is not greater than a thickness of the flange in the cap body 1. [0096] In a possible implementation, referring to Fig. 14 in conjunction with Fig. 15, the mounting seat 330 is provided with a positioning convex ring 333. When the cap body 1 is sucked onto the cap-sucking mechanism 300, an inner side surface of the positioning convex ring 333 is in contact with an outer side surface of a flange in the cap body 1 so as to limit the position of the cap body 1. In order to prevent the positioning convex ring 333 from affecting the contact between the cap body 1 and the sleeve 2 during the capping operation, a height of the positioning convex ring 333 is not greater than a thickness of the flange in the cap body 1, that is, the height of the positioning convex ring 333 may be equal to the thickness of the flange in the cap body 1 (i.e., the film 12), or the height of the positioning convex ring 333 may be smaller than the thickness of the flange in the cap body 1 (i.e., the film 12).
[0097] In some embodiments, the positioning convex ring 333 is provided with a first notch 333a through which the flexible suction chuck 340 is exposed.
[0098] It should be noted that if a sensor detects a distance between the flexible suction chuck 340 and the sleeve 2 during the capping operation, the positioning convex ring 333 may affect the function realization of the sensor, so it is necessary to arrange a first notch 333a on the positioning convex ring 333 to expose the flexible suction chuck 340. In a possible implementation, referring to Fig. 15 in conjunction with Fig. 17, the positioning convex ring 333 is provided with two first notches 333a; of course, there may be one first notch 333a, and the arrangement position of the first notch 333a is mainly adapted to the position of the sensor. As illustrated in Fig. 17, due to the existence of these two first notches 333a, the positioning convex ring 333 is divided into two arc-shaped convex rings, and the positioning of the cap body 1 can also be realized.
[0099] In some embodiments, the cap-sucking mechanism 300 includes a plurality of suction anvils 310 and a mounting shaft for mounting the plurality of suction anvils 310, and the plurality of suction anvils 310 are annularly arranged around an axis of the mounting shaft. [00100] It should be understood that, in order to improve the production efficiency, the cap-sucking mechanism 300 includes a plurality of suction anvils 310 and a mounting shaft for mounting the plurality of suction anvils 310, and the plurality of suction anvils 310 are annularly arranged around an axis of the mounting shaft. The plurality of suction anvils 310 may be at different working positions, for example, some of the suction anvils 310 are at the sucking position, some of the suction anvils 310 are at the capping position, some of the suction anvils 310 are in the process of switching from the sucking position to the capping position, and some of the suction anvils 310 are in the process of switching from the capping position to the sucking position.
[00101] In some embodiments, the cap-pushing mechanism 200 includes a cap-pushing plate 210 and an annular-shaped positioning assembly 220; the annular-shaped positioning assembly 220 is cooperated with the cap-pushing plate 210 to form a positioning groove for cooperating with the cap body 1.
[00102] In a possible implementation, as illustrated in Fig. 18, the cap-pushing mechanism 200 includes a cap-pushing plate 210 and a cap-pushing driving part 240 in transmission connection with the cap-pushing plate 210, and the cap-pushing driving part 240 provides power for the cap-pushing plate 210. An annular-shaped positioning assembly 220 is arranged at a side of the cap-pushing plate 210 facing away from the cap-pushing driving part 240, that is, at a side of the cap-pushing plate 210 facing towards the cap-sucking mechanism 300. The annular-shaped positioning assembly 220 is cooperated with the cap-pushing plate 210 to form a positioning groove for cooperating with the cap body 1, and the positioning groove can position the cap body 1 inside the cap-pushing channel 102 to ensure the coaxial degree between the cap body 1 and the suction end 301, so that the cap-pushing mechanism 200 pushes the cap body 1 to the suction end 301 of the cap-sucking mechanism 300 without an offset, thereby ensuring the stable suction of the cap body 1 and preventing the cap body 1 from falling off.
[00103] In some embodiments, along a depth direction of the positioning groove, an opening size of the positioning groove is gradually decreased.
[00104] In a possible implementation, as illustrated in Fig. 19, an inner surface of the annular-shaped positioning assembly 220 is an inclined cone surface, so that the opening size of the positioning groove is gradually decreased along the depth direction of the positioning groove. In the process of pushing the cap body 1 towards the cap-sucking mechanism 300, the cap-pushing mechanism 200 realizes the function of centrally positioning the cap body 1 corresponding to the suction end 301.
[00105] In some embodiments, the annular-shaped positioning assembly 220 includes a plurality of arc-shaped positioning plates 221, and the plurality of arc-shaped positioning plates 221 are annularly arranged around an edge of the cap-pushing plate 210.
[00106] In a possible implementation, in order to shorten a stroke of the cap-pushing plate 210 and to centrally position the cap body 1, as illustrated in Figure 19, the annular-shaped positioning assembly 220 is configured as a plurality of arc-shaped positioning plates 221 arranged annularly at intervals, which is similar to a claw structure. In this way, the cap body 1 can fall into the cap-pushing channel 102 by passing through a gap between two adjacent arcshaped positioning plates 221, so that the cap-pushing plate 210 inside the cap-pushing channel 102 has no need of retreating for reserving a length of the annular-shaped positioning assembly 220.
[00107] In some embodiments, the cap-pushing plate 210 is provided with a stopping plate 230 which is orientated towards the cap-feeding inlet 101 and configured to bear the cap body 1, and the stopping plate 230 is located at a side of the cap-pushing plate 210 facing away from the annular-shaped positioning assembly 220.
[00108] It should be noted that, with reference to Fig. 4, the cap body 1 enters the cappushing channel 102 through the cap-feeding inlet 101 located above the cap-guiding mechanism 100 by the action of its own gravity only, and there is a plurality of cap bodies 1 arranged in sequence along the direction of gravity. Therefore, during the process of the cappushing mechanism 200 pushing the previous cap body 1 that falls into the cap-pushing channel 102 to the suction end 301 of the cap-sucking mechanism 300, the next cap body 1 begins to fall under the action of its own gravity. In order to prevent the cap body 1 from falling onto the side of the cap-pushing plate 210 facing away from the cap-sucking mechanism 300, the cappushing plate 210 is provided with a stopping plate 230 which is orientated towards the capfeeding inlet 101 and used for receiving the next cap body 1 to be pushed, as illustrated in Figs. 18 and 19.
[00109] In some embodiments, in order to be adapted to an outer contour of the cap body 1, as illustrated in Fig. 19, the stopping plate 230 is formed with an arc-shaped bearing surface which is orientated towards the cap-feeding inlet 101.
[00110] It should be understood that, as illustrated in Fig. 20, the cap-pushing channel 102 of the cap-guiding mechanism 100 only needs to be adapted to outer contours of the cap- pushing plate 210 and the annular-shaped positioning assembly 220 of the cap-pushing mechanism 200.
[00111] In some embodiments, as illustrated in Fig. 21, when the cap-sucking mechanism 300 is at the capping position, the suction end 301 of the cap-sucking mechanism 300 is located at a side of the cap-guiding mechanism 100 facing away from the cap-feeding inlet 101; the side of the cap-guiding mechanism 100 facing away from the cap-feeding inlet 101 is provided with a second notch 103 for avoiding the cap-sucking mechanism 300, so as to prevent the cap-sucking mechanism 300 from contacting with the cap-guiding mechanism 100 in the process of the cap-sucking mechanism 300 switching from the capping position to the sucking position, thereby optimizing a path along which the cap-sucking mechanism 300 is switched from the capping position to the sucking position and hence saving the cycle time.
[00112] In some embodiments, as illustrated in Fig. 22, the capping device further includes a vacuum generator 500, and the vacuum generator 500 is communicated with the air suction channel 311 of the suction anvil 310.
[00113] It should be understood that the capping device provided by the embodiment of the present disclosure also includes devices such as sensors and processors to complete the capping operation, thus realizing automatic production and saving manpower.
[00114] In the second aspect, the embodiment of the present disclosure also provides a capping method, which specifically includes the following steps.
[00115] S2301, feeding a cap body into a cap-pushing channel through a cap-feeding inlet of a cap-guiding mechanism;
[00116] S2302: arranging a cap-sucking mechanism at a sucking position, and pushing the cap body inside the cap-pushing channel to a suction end of the cap-sucking mechanism by a cap-pushing mechanism;
[00117] S2303: sucking the cap body and conveying the same to a capping position to stay for a preset time by the cap-sucking mechanism, and switching the cap-sucking mechanism from the capping position to the sucking position.
[00118] In some embodiments, before switching the cap-sucking mechanism from the capping position to the sucking position, the capping method further includes:
[00119] determining whether a vacuum degree of a vacuum generator satisfies a preset range, so as to prevent the cap body from falling off due to insufficient suction force during the switching process of the cap-sucking mechanism.
[00120] In some embodiments, as illustrated in Fig. 24, an action path via arrows E and F, along which the cap-sucking mechanism is switched from the capping position to the sucking position is in an L shape, and an opening of the L shape is orientated towards the cap-guiding mechanism, thereby saving the cycle time as compared with the path in the figure.
[00121] In some embodiments, as illustrated in Fig. 25, an action path G along which the cap-sucking mechanism is switched from the capping position to the sucking position is in an arc shape, and an opening of the arc shape is orientated towards the cap-guiding mechanism, thereby saving the cycle time as compared with the path in the figure.
[00122] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present disclosure without departing from the spirit and scope of the present disclosure. Thus, it is intended that the present disclosure includes these modifications and variations provided that they are within the scope of the claims and their equivalents.
