Description

Technical Field

[0001] This application relates to the field of container encapsulation equipment, and particularly to an online installation device for bag mouth covers. Background Art

[0002] Capping devices are widely used in industries such as food, beverage, and pharmaceuticals. Especially on automated production lines, they are used to accurately install various types of mouth covers onto containers. Such devices not only improve the efficiency of the production line, reduce the cost of manual operation, but also significantly enhance the quality and consistency of products. With the growth of market demand and the progress of technology, the existing capping devices have also been continuously optimized and improved in terms of functionality and reliability.

[0003] Currently, in order to achieve the automatic installation of mouth covers, the common technical means is mainly to use a robotic arm to grab the mouth cover and cover it on the container. However, in practice, there may be a certain mating relationship between the mouth cover and the container. For example, the connection method between the mouth cover and the container is snap connection or threaded connection. To ensure a smooth snap connection between the two or prevent excessive rotation of the mouth cover during subsequent screwing, the mouth cover may need to be docked with the container in a specific posture. Another example is that there may be manufacturer logos or other patterns on the mouth cover and the container. For aesthetic considerations, the mouth cover may also need to be docked with the container in a specific posture. In the above situations, the traditional capping method also has problems in achieving high-precision positioning and posture adjustment. Summary of the Invention

[0004] In order to solve the problem that it is difficult to achieve high-precision positioning and posture adjustment in the traditional capping method, this application provides an online installation device for bag mouth covers.

[0005] An online installation device for bag mouth covers provided by this application adopts the following technical solutions: An online installation device for bag mouth covers includes a first conveying mechanism, a placement table, a vision detection component, an adjustment component, and a capping component; The first conveying mechanism is connected to the placement table and is used to convey the mouth cover to the placement table; The adjustment component is used to adjust the position and posture of the mouth cover located on the placement table. The mouth cover has a positioning portion for abutting against the adjustment component; The vision detection component is connected to the capping component and is used to identify the position of the container; The capping component is used to grab the mouth cover located on the placement table and cover the mouth cover on the container.

[0006] By adopting the above technical solutions, it is possible to achieve automatic conveying, position and posture adjustment of the mouth cover, identification of the container position, and precise capping of the mouth cover, improving production efficiency and automation level, and reducing the cost and error of manual operation.

[0007] Preferably, the adjusting assembly includes a driving unit and two abutting units, and the abutting units are respectively arranged on opposite sides of the access cover placed on the placing table. The driving unit is connected to the two abutting units and is used to drive the two abutting units to approach or move away from each other.

[0008] By adopting the above technical solution, accurate adjustment of the position and posture of the access cover can be achieved, ensuring that the access cover can be accurately grasped by the capping assembly and covered on the container, improving production efficiency and product quality. Specifically, the driving unit drives the two abutting units to approach each other and clamp the access cover, thereby adjusting the position of the access cover so that the access cover is always in the best state to be grasped. At the same time, this design can also adapt to access covers of different sizes and shapes, enhancing the versatility and flexibility of the equipment.

[0009] Preferably, along the direction perpendicular to the central axis of the access cover, the outer edge trajectory of the cross-section of the positioning portion is not circular; The abutting unit is an abutting block, and abutting grooves are provided on one side of each of the two abutting blocks facing each other, and the shape of the abutting groove is adapted to the positioning portion.

[0010] By adopting the above technical solution, when the outer edge trajectory of the cross-section of the positioning portion is not circular, accurate position and posture adjustment of the access cover can be achieved. Specifically: When the two abutting blocks approach each other and clamp the positioning portion of the access cover, the positioning portion can fall into the abutting groove and fit with the inner wall of the abutting groove to complete the position adjustment of the access cover.

[0011] The design of the outer edge trajectory of the cross-section of the positioning portion as non-circular enables the abutting groove on the abutting block to change the posture of the access cover when clamping the access cover and adjust the posture of the access cover to be completely fitted with the inner wall of the abutting groove.

[0012] Preferably, the vision detection assembly is further used to identify the postures of the access cover and the container; The adjusting assembly further includes a first rotating unit, and the first rotating unit is connected to the placing table and is used to drive the placing table to rotate.

[0013] By adopting the above technical solution, the vision detection assembly can detect the posture of the container, so that the container does not need to be placed in a specific posture in advance. The adjusting assembly can drive the placing table to rotate according to the actual posture of the container, thereby flexibly adjusting the posture of the access cover to facilitate the accurate docking of the access cover and the container.

[0014] Preferably, along the direction perpendicular to the central axis of the access cover, the outer edge trajectory of the cross-section of the positioning portion is circular; The abutting unit includes a mounting frame and a plurality of rotating wheels, and the plurality of rotating wheels are all rotatably arranged on the mounting frame, and the rotating wheels are used to abut against the positioning portion.

[0015] By adopting the above technical solution, accurate positioning of the cover can be achieved. Specifically: The abutting unit includes a mounting frame and a plurality of rotating wheels. The rotating wheels can rotate freely on the mounting frame and abut against the positioning portion. This design can effectively avoid jamming or damage caused by friction during the adjustment of the cover.

[0016] Preferably, the vision detection component is further used to identify the postures of the cover and the container; The adjustment component further includes a second rotation unit, and the second rotation unit is connected to at least one of the rotating wheels and is used to drive the rotating wheels to rotate.

[0017] By adopting the above technical solution, after the position of the cover is adjusted, the second rotation unit can drive the rotating wheels to rotate, thereby further adjusting the posture of the cover, improving the adjustment accuracy and efficiency, and ensuring the success rate and stability of the capping operation.

[0018] Preferably, the adjustment component further includes a lifting unit, and the lifting unit is connected to the placing table and is used to drive the placing table to lift.

[0019] By adopting the above technical solution, the lifting unit can realize the height adjustment of the placing table, thereby adjusting the cover to a preset height, ensuring that the cover is in a suitable position before being grabbed, and improving the stability and success rate of the capping process.

[0020] Preferably, the online cover mounting device for packaging bags further includes a material blocking component, and the material blocking component includes a first air cylinder and a second air cylinder arranged on the first conveying mechanism. The first air cylinder and the second air cylinder are jointly used to block some of the covers on the first conveying mechanism, so that a preset number of the covers are conveyed to the placing table.

[0021] By adopting the above technical solution, the number of covers on the placing table can be effectively controlled, and it is avoided that too many or too few covers affect the normal progress of subsequent processes. At the same time, the setting of the first air cylinder and the second air cylinder makes the material blocking operation more flexible and reliable, and improves the production efficiency and the operation stability of the equipment.

[0022] Preferably, the online cover mounting device for packaging bags further includes a limiting plate, and the limiting plate is arranged above the first conveying mechanism. The limiting plate is provided with a limiting groove along the conveying direction of the first conveying mechanism, and the positioning portion of the cover penetrates through the limiting groove.

[0023] By adopting the above technical solution, the limiting plate is arranged above the first conveying mechanism, and a limiting groove along the conveying direction of the first conveying mechanism is arranged on the limiting plate. The positioning part of the mouth cover is inserted into the limiting groove, which can effectively prevent the mouth cover from shifting or toppling during the conveying process, ensuring that the mouth cover is accurately conveyed to the placing table. Moreover, when the outer trajectory of the cross-section of the positioning part is non-circular, the limiting groove can also ensure that the mouth cover is conveyed in a specific posture, completing the preliminary posture adjustment of the mouth cover, and improving the working efficiency and reliability of the packaging bag mouth cover on-line installation device.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the adjusting component, the position and posture of the mouth cover can be accurately adjusted, ensuring that the mouth cover is stably and accurately aligned with the container on the placing table, thereby improving the accuracy and success rate of capping. 2.

[0030] The following further elaborates on this application Figures 1 to 4 in conjunction with the accompanying drawings.

[0031] Embodiment 1

[0032] As Figures 1 to 2 shown, an online installation device for a manhole cover of a packaging bag disclosed in an embodiment of this application includes a first conveying mechanism 1, a second conveying mechanism 2, a workbench 3, a placement table 31, a visual inspection assembly 4, an adjustment assembly 5, and a gland assembly 6.

[0033] Specifically, the first conveying mechanism 1 is used to convey the manhole cover 200, and the second conveying mechanism 2 is used to convey the container. The first conveying mechanism 1 and the second conveying mechanism 2 can be conveyor belts or other conventional conveying members. The container is a packaging bag, and other types of containers such as bottles can also be selected according to actual needs.

[0034] The placement table 31 is movably arranged on the workbench 3, and the top of the placement table 31 is a horizontal plane. The first conveying mechanism 1 is connected to the placement table 31, so that the manhole cover 200 can be conveyed to the placement table 31.

[0035] A limiting plate 11 is further arranged above the first conveying mechanism 1 and is connected thereto. The limiting plate 11 is provided with a limiting groove 111 along the conveying direction of the first conveying mechanism 1. At least a part of the manhole cover 200 is inserted into the limiting groove 111. By limiting the manhole cover 200 through the limiting groove 111, it can be ensured that the first conveying mechanism 1 accurately conveys the manhole cover 200 to a preset area on the placement table 31, completing the preliminary positioning of the manhole cover 200.

[0036] Furthermore, the manhole cover 200 has a positioning portion 201, and the positioning portion 201 is inserted into the limiting groove 111. When the outer edge trajectory of the cross-section of the positioning portion 201 is not circular in the direction perpendicular to the central axis of the manhole cover 200, the limiting function of the limiting groove 111 can ensure that the positioning portion 201 is conveyed in a specific posture, completing the preliminary posture adjustment of the manhole cover 200.

[0037] Further, the on-line installation device for the bag mouth cover further includes a material blocking assembly 7. The material blocking assembly 7 includes a first cylinder 71 and a second cylinder 72 horizontally arranged on the first conveying mechanism 1. The first cylinder 71 and the second cylinder 72 are jointly used to block some of the mouth covers 200 on the first conveying mechanism 1, so that a preset number of mouth covers 200 are conveyed to the placing table 31.

[0038] Taking the preset number as one for example, the second cylinder 72 is located at one end of the first conveying mechanism 1 close to the placing table 31. The second cylinder 72 can block all the mouth covers 200 on the first conveying mechanism 1 by extending. After the mouth covers 200 are blocked, under the action of the first conveying mechanism 1, the mouth covers 200 on the first conveying mechanism 1 can be gathered in sequence and stick to each other. At this time, the first cylinder 71 extends, so that one (preset number) of the mouth covers 200 is limited between the piston of the first cylinder 71 and the piston of the second cylinder 72. Then, the second cylinder 72 retracts, and the foremost one of the mouth covers 200 can be conveyed to the placing table 31 under the action of the first conveying mechanism 1.

[0039] The adjusting assembly 5 is used to adjust the position and posture of the mouth cover 200 located on the placing table 31. The adjusting assembly 5 includes a driving unit 51 and two abutting units 52. The driving unit 51 can be two third cylinders, and the two third cylinders are connected to the two abutting units 52 in a one-to-one correspondence.

[0040] Relative to the mouth cover 200 placed on the placing table 31, the two abutting units 52 are respectively located on its opposite sides. The driving unit 51 is connected to the two abutting units 52, and the driving unit 51 can drive the two abutting units 52 to approach or move away from each other, so as to adjust the position of the mouth cover 200.

[0041] For example, the abutting unit 52 is an abutting block 521. When the two abutting blocks 521 approach each other, they can abut against the positioning part 201 of the mouth cover 200. An abutting groove 5211 is provided on one side of each of the two abutting blocks 521 facing the other. The shape of the abutting groove 5211 is adapted to the positioning part 201. When the two abutting blocks 521 abut against and clamp the mouth cover 200, the positioning part 201 of the mouth cover 200 can fall into the abutting groove 5211 and fit fully with the inner wall of the abutting groove 5211, so as to complete the precise fine adjustment of the position of the mouth cover 200. Moreover, when the outer edge track of the cross-section of the positioning part 201 is not circular along the direction perpendicular to the central axis of the mouth cover 200, the abutting block 521 can also adjust the posture of the mouth cover 200 when clamping the mouth cover 200. Thus, the mouth cover 200 is adjusted to a preset posture, which is convenient for subsequent docking of the mouth cover 200 with a container in a specific posture.

[0042] The vision detection component 4 is connected to the capping component 6 and is used to identify the position of the container, facilitating the capping component 6 to grasp the cover 200 located on the placement table 31 and accurately cap the cover 200 on the container.

[0043] Furthermore, the vision detection component 4 is also used to identify the posture of the cover 200 and the container. By identifying the postures of the cover 200 and the container, the container does not need to be placed in a specific posture in advance. The adjustment component 5 can flexibly adjust the posture of the cover 200 according to the posture of the container to ensure that the cover 200 can adapt to containers in various postures. Among them, the vision detection component 4 may include an industrial camera and a controller. The industrial camera, the adjustment component 5, and the capping component 6 are all connected to the controller. After the industrial camera captures images of the container and the cover 200 and the controller analyzes the position and posture information, the controller first controls the adjustment component 5 to adjust the position and posture of the cover 200, and then controls the capping component 6 to grasp the cover 200 and cap the cover 200 on the container.

[0044] In addition, since when the container is not pre-placed in a specific posture, it may not be possible to meet the posture adjustment requirements of the cover 200 only through the abutting unit 52. Therefore, in this embodiment, the adjustment component 5 is further provided with a first rotation unit 53. The first rotation unit 53 is connected to the placement table 31 and is used to drive the placement table 31 to rotate. After the abutting unit 52 positions the cover 200, the central axis of the cover 200 is collinear with the rotation axis 532 of the placement table 31. By driving the placement table 31 to rotate through the first rotation unit 53, the posture of the cover 200 can be changed. Among them, the first rotation unit 53 includes a first motor 531 and a rotating shaft 532. The rotating shaft 532 is rotatably connected to the placement table 31, and one end of the rotating shaft 532 is connected to the first motor 531, and the other end is connected to the placement table 31.

[0045] Furthermore, the adjustment component 5 is further provided with a lifting unit 54. The lifting unit 54 is connected to the placement table 31 and is used to drive the placement table 31 to lift. For example, the lifting unit 54 may include a fourth cylinder 541 and a lifting plate 542. The lifting plate 542 is slidably arranged on the workbench 3. The lifting plate 542 can be regarded as a part of the workbench 3. The first motor 531 and the rotating shaft 532 are both arranged on the lifting plate 542. The fourth cylinder 541 is vertically arranged and connected to the lifting plate 542. By telescoping, it drives the lifting plate 542 to lift, and then drives the placement table 31 to lift. By driving the placement table 31 to lift, it can not only enable the cover 200 on the first conveying mechanism 1 to smoothly reach the placement table 31, but also adjust the cover 200 on the placement table 31 to a suitable height, facilitating the subsequent capping component 6 to accurately grasp the cover 200 and accurately cap the cover 200 on the container.

[0046] The gland assembly 6 can be a robotic arm or a conventional multi-axis drive mechanism. For example, the multi-axis drive mechanism includes an X-axis guide rail 61, a Z-axis guide rail 62, a first slide 63, a second slide 64, a gripping member 65, and two sets of drive modules 66. Among them, the X-axis guide rail 61 is horizontally arranged, the first slide 63 is slidably arranged on the X-axis guide rail 61, and one set of drive modules 66 drives the first slide 63 to slide along the X-axis guide rail 61. The Z-axis guide rail 62 is vertically arranged on the first slide 63, and the second slide 64 is slidably arranged on the Z-axis guide rail 62. The other set of drive modules 66 is used to drive the second slide 64 to slide along the Z-axis guide rail 62. The gripping member 65 and the vision detection assembly 4 are both arranged on the second slide 64. Through the mutual cooperation of the two sets of drive modules 66, the gripping member 65 and the vision detection assembly 4 can be driven to move. Among them, the gripping member 65 is used to grip the access cover 200, and the gripping member 65 can be a clamping jaw cylinder. The drive module 66 can include a motor and a lead screw. The specific setting is a conventional technology and will not be elaborated.

[0047] Embodiment 2

[0048] The difference between this embodiment and the above embodiment is that the adjustment assembly 5 is improved.

[0049] Specifically, as Figures 3 to 4 shown, the abutting unit 52 includes a mounting bracket 522 and a plurality of rotating wheels 523. The plurality of rotating wheels 523 are all rotatably arranged on the mounting bracket 522. The axis of the rotating wheel 523 is parallel to the axis of the access cover 200 on the placement table 31. The driving unit 51 is connected to the mounting bracket 522. The driving unit 51 can drive the mounting bracket 522 to move, so that the plurality of rotating wheels 523 are simultaneously abutted against the positioning portion 201 of the access cover 200 to complete the positioning of the access cover 200.

[0050] Moreover, when the outer edge trajectory of the cross-section of the positioning portion 201 is circular along the direction perpendicular to the central axis of the access cover 200, it can be set that the adjustment assembly 5 further includes a second rotating unit 55. The second rotating unit 55 is connected to at least one rotating wheel 523 and is used to drive the rotating wheel 523 to rotate. When the rotating wheel 523 rotates, the access cover 200 can also rotate following the rotating wheel 523, so that the attitude of the access cover 200 can be changed. The advantages of changing the attitude of the access cover 200 by driving the rotating wheel 523 to rotate are as follows: 1. The access cover 200 is always in a state of being limited by the rotating wheel 523 during the attitude change process, and the position of the access cover 200 will not change. 2. There is no need to drive the placement table 31 to rotate to adjust the attitude of the access cover 200. Even if there are multiple access covers 200 on the placement table 31, the attitudes of multiple access covers 200 can still be adjusted simultaneously by reasonably setting the number of the first rotating unit 53 and the rotating wheels 523.

[0051] Among them, the second rotating unit 55 includes a second motor 551, a belt 552, and two belt pulleys 553. The second motor 551 is disposed on the mounting bracket 522. One of the belt pulleys 553 is sleeved on the central shaft of the rotating wheel 523, and the other belt pulley 553 is sleeved on the output shaft of the second motor 551. The two belt pulleys 553 are drivingly connected by the belt 552.

[0052] In this embodiment, since it is not necessary to rotate the placement table 31 to adjust the attitude of the hatch 200, in this embodiment, the lifting unit 54 may only include a fourth cylinder 541, and the lifting unit 54 is directly connected to the placement table 31 and drives the placement table 31 to lift and lower.
