Description

Technical Field

[0001] The present application relates to the technical field of tightening bottle caps, and in particular to a device for tightening bottle caps through a positioning loop. Background Art

[0002] The capping device is a mechanical device commonly used in the food and pharmaceutical fields. During use, the bottle cap on the bottle body passes through two rollers arranged at intervals, thereby rotating the bottle cap to tighten the bottle cap, or the bottle cap is clamped by a mechanical arm and tightened onto the bottle body.

[0003] In the prior art, when the bottle cap is screwed onto the bottle, due to the limitation of the threads on the bottle cap and the bottle, the initial height of the bottle cap placed on the bottle at different angles is different, so that the screwing height required to screw the bottle cap onto the bottle is different. Therefore, after screwing the bottle cap, the bottle cap is easily screwed too tight or too loose. Utility Model Content

[0004] In order to reduce the probability of the bottle cap being over-tightened or over-loosened, the present application provides a device for tightening the bottle cap through a positioning loop.

[0005] The present application provides a device for tightening a bottle cap through a positioning loop line, which adopts the following technical solution:

[0006] A device for tightening a bottle cap through a positioning ring line, comprising:

[0007] A marking device is arranged close to the moving path of the bottle body, the marking device comprises a color ring nozzle, the color ring nozzle is arranged toward the bottle body, and the height of the color ring nozzle is parallel to the tightening height of the bottle cap;

[0008] A capping device, located behind the marking device along the moving direction of the bottle body, and used for tightening the bottle cap onto the bottle body;

[0009] The detection device is arranged close to the cap screwing device, the detection device is connected to the cap screwing device, the arrangement height of the detection device is consistent with the height of the color ring nozzle, the detection device can control the start and stop of the cap screwing device, and the detection device can detect the color ink sprayed on the bottle body by the color ring nozzle.

[0010] By adopting the above technical solution, when the bottle moves through the marking device, the color ring nozzle in the marking device can spray color ink onto the bottle, so that a color band is formed on the bottle, and the position of the color band corresponds to the position where the bottle cap is just tightened. When the bottle with the color band formed passes through the capping device, the capping device can tighten the bottle cap onto the bottle, and at the same time, the detection device detects the color band formed by the color ink in the color ring nozzle on the bottle. When the bottle cap covers the color band on the bottle, causing the color band detected by the detection device to change, the detection device controls the capping device to stop screwing the cap, so that the bottle cap stops in a just tightened state, thereby reducing the probability of the bottle cap being over-tightened or too loose.

[0011] Optionally, the color ring nozzle includes a first color ring nozzle and a second color ring nozzle, the first color ring nozzle is arranged above the second color ring nozzle along the height direction of the bottle body, and the first color ring nozzle and the second color ring nozzle respectively spray ink of different colors onto the bottle body.

[0012] By adopting the above technical solution, the first color ring nozzle and the second color ring nozzle are arranged along the height direction of the bottle body respectively, and they are allowed to spray inks of different colors. The two marks of different colors can provide more detailed information about the tightening status of the bottle cap, so that the operator can control the tightening process more accurately, thereby improving the positioning accuracy.

[0013] Optionally, the marking device further includes a height adjustment mechanism, which is arranged along the height direction of the bottle body, connected to the color ring nozzle, and used to drive the color ring nozzle to move along the height direction of the bottle body.

[0014] By adopting the above technical solution, the height adjustment mechanism increases the adaptability of the device to bottles of different heights. The same device can adapt to bottles of different sizes and can handle bottles of various heights without changing the device, greatly improving the versatility and flexibility of the device. At the same time, by adjusting the height of the color ring nozzle, it can be ensured that the color ribbon is exactly in the ideal position when the bottle cap is tightened on the bottle, thereby improving the tightening accuracy, ensuring the sealing effect of the bottle cap, and reducing the risk of the bottle cap being tightened too tight or too loose. In addition, the height adjustment mechanism also enhances the degree of automation of the device. In an automated production line, the position of the color ring nozzle can be automatically adjusted according to the actual height of the bottle body, so that bottles of different heights can be processed continuously without manual intervention, thereby improving production efficiency.

[0015] Optionally, the height adjustment mechanism includes a limit plate and an adjusting cylinder, the fixed end of the adjusting cylinder is fixedly connected to one end of the limit plate, the telescopic end of the adjusting cylinder is fixedly connected to one end of the color ring nozzle, the limit plate is provided with an adjustment groove, and the side of the color ring nozzle facing away from the bottle body is slidably connected in the adjustment groove.

[0016] By adopting the above technical solution, the adjustment cylinder allows for fine control of the height of the color ring nozzle, so that the nozzle can be quickly and accurately adjusted according to different bottle heights, which is essential for achieving precise spraying. In addition, through the combination of the limit plate and the adjustment slot, the color ring nozzle remains stable during the height adjustment process, reducing the offset or vibration during operation, thereby ensuring the consistency and accuracy of the spraying. In addition, the adjustment cylinder can automatically adjust the height according to preset parameters or real-time feedback, improving production efficiency and reducing manual intervention.

[0017] Optionally, the capping device includes a capping caliper and a movable arm, one end of the capping caliper is arranged toward the bottle body, the movable arm is connected to the end of the capping caliper away from the bottle body, and the movable arm and the capping caliper are electrically connected to the detection device.

[0018] By adopting the above technical solution, the design of the capping caliper facing the bottle body makes the mechanical contact with the bottle cap more direct, thereby improving the accuracy of tightening the bottle cap. Direct contact ensures the uniformity and controllability of the capping force, thereby improving the consistency and reliability of the cap sealing. Secondly, the moving arm allows the capping caliper to be adjusted when necessary to adapt to bottle caps in different positions. This is crucial for adapting to bottles of different sizes and shapes, and improves the versatility of the equipment and its ability to adapt to different production lines. In addition, the capping caliper and the moving arm are electrically connected to the detection device, providing a real-time feedback and adjustment mechanism for the capping process. This connection ensures that once the detection device finds that the tightening state of the bottle cap has reached the ideal condition, it can immediately instruct the capping caliper to stop tightening, thereby avoiding the situation where the bottle cap is over-tightened or too loose.

[0019] Optionally, the detection device includes a detection camera and a moving mechanism, the detection camera is arranged toward the color ring sprayed by the color ring nozzle on the bottle body, and the moving mechanism is connected to a side of the detection camera facing away from the bottle body.

[0020] By adopting the above technical solution, when the bottle cap is screwed, the detection camera can detect the color ring on the bottle body. When the bottle cap covers one of the color rings, the detection device sends a signal to the cap screwing device, thereby stopping the tightening of the bottle cap, so that the bottle cap is just tightened. Through the moving mechanism, the detection camera can be moved in the height direction of the bottle body, so that when corresponding to bottles of different sizes and color rings in different positions, the position of the detection camera can also be adjusted to the corresponding height to realize the detection of the color ring.

[0021] Optionally, the moving mechanism includes a support plate, an adjusting screw and an adjusting nut, the support plate is provided with a moving groove in the direction toward the bottle body, the adjusting nut is fixedly connected to the side of the detection camera facing away from the bottle body and is slidably connected to the groove wall of the moving groove, the adjusting screw is arranged along the height direction of the bottle body, and the adjusting screw is cooperatively connected with the adjusting nut.

[0022] By adopting the above technical solution, the position of the detection camera can be finely adjusted by adjusting the combination of the screw rod and the adjusting nut to adapt to bottles of different heights or different capping process requirements, ensuring that the camera can be positioned in the best position to capture the color ring sprayed by the color ring nozzle, thereby improving the accuracy and reliability of the detection. Secondly, the moving groove on the support plate allows the adjusting nut to move along a specific path, increasing the structural stability of the device while ensuring the linearity and smoothness of the camera movement. In addition, this design supports quick and convenient adjustment or replacement of the detection camera. When the production line needs to adapt to different products or when the detection equipment needs maintenance, the staff can easily adjust or replace the camera without the cumbersome disassembly process, thereby reducing production downtime.

[0023] Optionally, a device for tightening a bottle cap by means of a positioning ring line further comprises a rotating device, wherein the rotating device is arranged close to the marking device, and the rotating device is used for driving the bottle body to rotate.

[0024] By adopting the above technical solution, the rotating device allows the bottle body to rotate in a fixed position, allowing the color ring nozzle and the detection camera to spray and detect the bottle body evenly and accurately during the rotation of the bottle body. This continuous rotation method is more efficient than the method of moving the bottle body to different stations for processing, which can significantly improve the overall speed and efficiency of the production line. At the same time, the rotation of the bottle body ensures the uniform application and comprehensive detection of the color ribbon. The color ring nozzle can spray around the bottle body at the same height, forming a complete loop, rather than just on one side or part of the bottle body. Similarly, the detection camera can fully monitor the color ribbon on the bottle body, ensuring the correct alignment between the bottle cap and the color ribbon after tightening.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Before screwing the bottle cap, the bottle body passes through the marking device, and the color ink is sprayed onto the bottle body through the color ring nozzle to form a color band, so that the position of the color band corresponds exactly to the position where the bottle cap is tightened. The detection camera detects the color band on the bottle body when the capping device tightens the bottle cap. When the color band on the bottle body changes due to the covering of the bottle cap, the detection device controls the capping device to stop tightening the bottle cap, so that the bottle cap stays in a just tightened state, thereby reducing the probability of the bottle cap being over-tightened or too loose;

[0027] 2. The first color ring nozzle and the second color ring nozzle are arranged to form the first color ring and the second color ring on the bottle body. When tightening the bottle cap, when the detection device detects that one of the color rings is covered by the bottle cap, the cap tightening device will be stopped immediately, so that the bottle cap can be in a properly tightened state. When verifying the tightening state of the bottle cap, the state of the color band exposed outside can be observed to directly determine whether the bottle cap is properly tightened. If exactly one color band is exposed outside, the bottle cap is in a properly tightened state;

[0028] 3. When dealing with bottles of different sizes, the height at which the bottle cap is tightened is also different. The height of the color ring nozzle can be adjusted by adjusting the cylinder, so that the color ring can be sprayed at the exact tightening position of the bottle cap on the corresponding bottle, thereby achieving the tightening of the bottle cap on bottles of different sizes.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a device for tightening a bottle cap through a positioning loop. Figure 1 and Figure 2 A device for tightening a bottle cap through a positioning ring line includes a marking device 1, a cap tightening device 2 and a detection device 3.

[0036] The marking device 1 is located on one side of the bottle moving path. The marking device 1 includes a color ring nozzle 11. The color ring nozzle 11 is arranged directly opposite the bottle and sprays color ink on the bottle. The color ring nozzle 11 is at a height where the bottle cap is just tightened. The capping device 2 is located behind the marking device 1 along the bottle moving direction. The capping device 2 is used to tighten the bottle cap on the bottle. The detection device 3 is arranged directly opposite the bottle. The detection device 3 detects the color ink on the bottle at the position where the capping device 2 screws the bottle cap. The detection device 3 is electrically connected to the capping device 2. The arrangement height of the detection device 3 is consistent with the height of the color ring nozzle 11.

[0037] When the bottle body passes through the marking device 1, the marking device 1 can spray colored ink to the position on the bottle body where the bottle cap is just tightened, thereby forming a color band on the bottle body. Afterwards, the bottle body passes through the capping device 2, which tightens the bottle cap on the bottle body. At the same time, the detection device 3 detects the color band on the bottle body. When the color band on the bottle body changes due to the tightening of the bottle cap, the detection device 3 controls the capping device 2 to stop tightening the bottle cap, thereby stopping the bottle cap at the just tightened position, thereby reducing the probability of the bottle cap being over-tightened or too loose.

[0038] Reference Figure 1 and Figure 2 A device for tightening a bottle cap by a positioning loop also includes a rotating device 4, which is arranged near the marking device 1 and is used to drive the bottle body to rotate. The rotating device 4 is arranged as a motor 42 and a rotating disk 41, and the arrangement direction of the rotating disk 41 is consistent with the moving direction of the bottle body and is located on the moving path of the bottle body. The motor 42 is located on the side of the rotating disk 41 away from the bottle body and is coaxially connected to the rotating disk 41.

[0039] When the bottle body passes through the turntable 41, the turntable 41 drives the bottle body to rotate. At the same time, the color ring nozzle 11 sprays color ink onto the bottle body. Therefore, under the joint action of the rotating device 4 and the marking device 1, a color ring can be formed at the position where the bottle cap is tightened on the bottle body, which facilitates the subsequent detection device 3 to detect the color ring on the bottle body from different angles.

[0040] Reference Figure 1 and Figure 2 The color ring nozzle 11 includes a first color ring nozzle 111 and a second color ring nozzle 112. The first color ring nozzle 111 is arranged above the second color ring nozzle 112 along the height direction of the bottle body. The first color ring nozzle 111 and the second color ring nozzle 112 are abutted on one side along the height direction of the bottle body. The first color ring nozzle 111 and the second color ring nozzle 112 respectively spray different colors of ink onto the bottle body.

[0041] When the color ring nozzle 11 is working, the first color ring nozzle 111 and the second color ring nozzle 112 respectively spray inks of different colors toward the bottle body, thereby forming two adjacent color rings of different colors on the bottle body. When the capping device 2 tightens the bottle cap, the detection device 3 can detect the two color rings. When one color ring is completely covered by the capping device 2, it means that the bottle cap has just reached the tightening position, and the detection mechanism can stop the capping action of the capping device 2 in time.

[0042] The marking device 1 further comprises a height adjustment mechanism 12, which is arranged along the height direction of the bottle body and connected to the color ring nozzle 11, and is used to drive the color ring nozzle 11 to move along the height direction of the bottle body.

[0043] The height adjustment mechanism 12 includes a limit plate 121 and an adjusting cylinder 122. The fixed end of the adjusting cylinder 122 is arranged near the end of the limit plate 121. The fixed end of the adjusting cylinder 122 is fixedly connected to the limit plate 121. The telescopic end of the adjusting cylinder 122 is arranged along the arrangement direction of the limit plate 121. The telescopic end of the adjusting cylinder 122 is fixedly connected to one end of the color ring nozzle 11. The limit plate 121 is provided with an adjusting groove 1211. The side of the color ring nozzle 11 facing away from the bottle body is slidably connected in the adjusting groove 1211. The adjusting groove 1211 is preferably arranged as a dovetail groove or a wedge groove.

[0044] When dealing with bottles of different sizes, the height at which the bottle cap is just tightened to the bottle body is also different. At this time, the height adjustment mechanism 12 can be used to make the color ring nozzle 11 slide in the adjustment groove 1211 to reach the position where the bottle cap is just tightened, thereby realizing the tightening of bottle caps of different sizes, so that bottles and bottle caps of different sizes can all reach a just tightened state, expanding the scope of use of a device for tightening bottle caps through a positioning ring line.

[0045] Reference Figure 1 and Figure 3 The capping device 2 includes a capping caliper 21 and a moving arm 22. The bottom end of the capping caliper 21 is arranged toward the bottle body. The moving arm 22 is connected to the top of the capping caliper 21. The moving arm 22 and the capping caliper 21 are both electrically connected to the detection device 3.

[0046] The capping caliper 21 can clamp the bottle cap and drive the bottle cap to rotate. The movable arm 22 can replace the capping caliper 21 to move up and down. Under the joint action of the capping caliper 21 and the movable arm 22, the bottle cap can be tightened on the bottle body. The detection device 3 is electrically connected with the movable arm 22 and the capping caliper 21. When the detection device 3 detects that the bottle cap is just tightened, the capping caliper 21 can be controlled to loosen the bottle cap, and the movable arm 22 can return the capping caliper 21 to its original position, so as to facilitate the tightening of the next bottle cap.

[0047] Reference Figure 1 and Figure 4 The detection device 3 includes a detection camera 31 and a moving mechanism 32. The detection camera 31 is arranged toward the color ring on the bottle body, and the moving mechanism 32 is fixedly connected to the side of the detection camera 31 away from the bottle body. The moving mechanism 32 includes a support plate 321, an adjusting screw rod 322, and an adjusting nut 323. The support plate 321 is provided with a moving groove 3211 on the side facing the bottle body, and the moving groove 3211 is arranged up and down. The adjusting nut 323 is fixedly connected to the side of the detection camera 31 away from the bottle body and is slidably connected to the groove wall of the moving groove 3211. The adjusting screw rod 322 is arranged along the height direction of the bottle body, and the adjusting screw rod 322 is matched and connected with the adjusting nut 323.

[0048] When dealing with bottles of different sizes, when the height of the color ring nozzle 11 changes and the height of the color ring sprayed on the bottle changes, the position of the detection camera 31 can be changed accordingly by adjusting the screw rod 322, so that the color ring is detected and the cap screwing device 2 is controlled so that the bottle cap can stay in the just tightened position.

[0049] The implementation principle of a device for tightening a bottle cap by a positioning ring line in an embodiment of the present application is as follows: before tightening the bottle cap, a marking device 1 is used to spray colored ink to the position on the bottle body where the bottle cap is just tightened, so that a color ring is formed on the bottle body, and then a capping device 2 tightens the bottle cap on the bottle body. When the capping device 2 tightens the bottle cap, a detection device 3 detects changes in the color ring on the bottle body. When the color ring on the bottle body is covered by the bottle cap, the detection device 3 controls the capping device 2 to stop tightening the cap, so that the bottle cap stays at the tightening position, thereby reducing the probability of the bottle cap being over-tightened or too loose.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
