Description

Technical Field

[0001] The invention belongs to the technical field of capping, and in particular relates to a double-station synchronous capping device and an adaptive control method. Background Art

[0002] In the bottles used in daily life, a bottle cap is usually used, which has a cover body and a lid, and the cover body has an outflow hole. This bottle cap is generally called a butterfly cover or butterfly cover. Before the bottle is packaged, it is necessary to use a box cover machine to cover the outflow hole on the cover body with this cover, so as to facilitate the subsequent screwing on the bottle to ensure its sealing state.

[0003] At present, in the past production practice, manual capping is mostly used for product packaging. Each manual capping action takes a certain amount of time, and it is difficult to maintain a high-speed and stable working state for a long time. The long-term and repeated capping operation puts a great burden on the workers' physical and mental state, and easily makes the capping personnel feel tired. In the fatigued state, the workers' attention is difficult to concentrate, and the accuracy and stability of the operation will be greatly reduced, which will lead to frequent failure of capping. Failure to cap in place will cause the product's sealing to fail to meet the standard, thereby affecting the product's use effect. Summary of the invention

[0004] The object of the present invention is to provide a dual-station synchronous capping device and an adaptive control method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a double-station synchronous capping device, comprising:

[0007] The optical fiber sensor is arranged at the bottom center of the push plate and is used to monitor the position of the positioning box.

[0008] Preferably, the surface of the frame is connected to a vertical frame, a first cylinder is provided on the top of the vertical frame, and a piston rod of the first cylinder movably penetrates the vertical frame and is connected to the push plate.

[0009] Preferably, the capping heads are provided in two groups and are both connected to the bottom of the push plate, the top of the push plate is connected to a guide rod and the other end of the guide rod slides through the stand.

[0010] Preferably, sliders are connected to both ends of the rubber block, and the rubber block is slidably connected to the chute in the gland head through the sliders. A plurality of springs are connected between the gland head and the rubber block.

[0011] Preferably, an arc-shaped groove is provided in the positioning box, and an arc-shaped block is slidably connected to one side of the arc-shaped groove. Slide bars are connected to both ends of the arc-shaped block, and the other ends of the slide bars slidably penetrate through the guiding grooves provided in the positioning box.

[0012] Preferably, a second cylinder is connected to one side of the positioning box through a protective shell, and the piston rod of the second cylinder movably penetrates through the positioning box and is connected to the arc-shaped block. Protective pads are provided on the surfaces of both the arc-shaped groove and the arc-shaped block.

[0013] Preferably, a control box is provided on the surface of the frame.

[0014] An adaptive control method for a double-station synchronous glanding device specifically includes the following steps:

[0015] S1. The fiber optic sensor real-time monitors the position of the positioning box. When the positioning box moves with the conveyor belt into the detection range of the fiber optic sensor, the fiber optic sensor sends a signal to the control box;

[0016] S2. After receiving the signal from the fiber optic sensor, the control box sends a start command to the first cylinder. The piston rod of the first cylinder extends, pushing the push plate downward, and then driving the gland head to move towards the double-opening lid in the positioning box;

[0017] S3. During the downward movement of the gland head, the rubber block gradually approaches the double-opening lid for lid closing. During the lid closing process, the fiber optic sensor continuously monitors the position change of the positioning box and the contact state between the rubber block and the double-opening lid to ensure the accuracy and stability of the lid closing operation.

[0018] S4. After the gland head completes the lid closing operation, the control box sends a reverse command to the first cylinder, and the piston rod of the first cylinder retracts, driving the push plate and the gland head to reset upward.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) By adopting a double-station design and cooperating with the conveyor belt and the positioning box, the glanding operation can be simultaneously performed on two double-opening lids.

[0021] (2)Precisely monitor the position of the positioning box through the fiber optic sensor to ensure that the capping head accurately aligns with the double-opening lid, improving the accuracy of capping. At the same time, the design of the arc-shaped groove, arc-shaped block, and protective pad in the positioning box can firmly fix the double-opening lid, preventing it from shifting during capping, thus effectively ensuring key quality indicators such as the product's sealing performance, reducing the defective rate, and improving the stability of product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a double-station synchronous capping device as shown in Figures 1-3 which includes:

[0028] A frame 1, in which a driving roller 2 and a driven roller 3 are respectively rotatably connected through bearings inside the top of the frame 1. A conveyor belt 4 is drivingly connected to the driving roller 2 and the driven roller 3. A plurality of positioning boxes 5 for fixing the double-opening lid are provided on the conveyor belt 4. A capping mechanism for closing the double-opening lid in the positioning box 5 is provided on the frame 1. The capping mechanism includes a push plate 6 and a capping head 7. The push plate 6 drives the capping head 7 to move, so that a rubber block 8 slidably connected to the bottom of the capping head 7 performs a capping operation on the double-opening lid;

[0029] A fiber optic sensor 9, which is provided at the center of the bottom of the push plate 6 and is used to monitor the position of the positioning box 5.

[0030] The surface of the frame 1 is connected to the vertical frame 10. A first cylinder 11 is provided at the top of the vertical frame 10, and the piston rod of the first cylinder 11 movably penetrates through the vertical frame 10 and is connected to the push plate 6.

[0031] Two sets of the gland heads 7 are provided and are both connected to the bottom of the push plate 6. A guide rod 12 is connected to the top of the push plate 6, and the other end of the guide rod 12 slidably penetrates through the vertical frame 10. The movement direction of the push plate 6 can be guided through the guide rod 12, strengthening the stability of the movement of the push plate 6.

[0032] Both ends of the rubber block 8 are connected with sliders, and the rubber block 8 is slidably connected to the chute in the gland head 7 through the sliders. A plurality of springs 13 are connected between the gland head 7 and the rubber block 8.

[0033] An arc-shaped groove 14 is provided in the positioning box 5, and an arc-shaped block 15 is slidably connected to one side of the arc-shaped groove 14. Both ends of the arc-shaped block 15 are connected with slide rods 16, and the other ends of the slide rods 16 slidably penetrate through a guide groove 17 provided in the positioning box 5. The guide groove 17 provides a specific movement path for the slide rods 16, enabling the arc-shaped block 15 to slide only along the direction of the guide groove 17, thereby precisely defining the movement track of the arc-shaped block 15 and ensuring the accuracy and stability of its movement.

[0034] One side of the positioning box 5 is connected with a second cylinder 18 through a protective shell, and the piston rod of the second cylinder 18 movably penetrates through the positioning box 5 and is connected to the arc-shaped block 15. Protective pads 19 are provided on the surfaces of the arc-shaped groove 14 and the arc-shaped block 15. The protective pads 19 are made of rubber and have softness and elasticity, avoiding scratches, abrasions or deformations and other damages on the surface of the double open lid caused by extrusion when the arc-shaped groove 14 and the arc-shaped block 15 fix the double open lid.

[0035] A control box 20 is provided on the surface of the frame 1.

[0036] An adaptive control method for a double-station synchronous glanding device specifically includes the following steps:

[0037] S1. The optical fiber sensor 9 monitors the position of the positioning box 5 in real time. When the positioning box 5 moves to the detection range of the optical fiber sensor 9 along with the conveyor belt 4, the optical fiber sensor 9 sends a signal to the control box 20;

[0038] S2. After the control box 20 receives the signal from the optical fiber sensor 9, it sends a start command to the first cylinder 11. The piston rod of the first cylinder 11 extends, pushing the push plate 6 to move downward, and then driving the gland head 7 to move towards the double open lid in the positioning box 5;

[0039] S3. During the downward movement of the capping head 7, the rubber block 8 gradually approaches the double-opening lid for lid closing. During the lid-closing process, the fiber optic sensor 9 continuously monitors the position change of the positioning box 5 and the contact state between the rubber block 8 and the double-opening lid to ensure the accuracy and stability of the lid-closing operation.

[0040] S4. After the capping head 7 completes the lid-closing operation, the control box 20 sends a reverse instruction to the first cylinder 11, and the piston rod of the first cylinder 11 retracts, driving the push plate 6 and the capping head 7 to reset upward.

[0041] For this double-station synchronous capping device and adaptive control method, the motor drives the driving roller 2 to rotate, and the driving roller 2 drives the conveyor belt 4 to operate through friction. The driven roller 3 plays an auxiliary supporting and guiding role. The positioning box 5 is installed on the conveyor belt 4 and moves with the conveyor belt 4. The double-opening lid to be capped is placed in the positioning box 5 through an external robotic arm. Then, the control box 20 controls the second cylinder 18 to start, so that the arc-shaped block 15 cooperates with the arc-shaped groove 14 in the positioning box 5 under the drive of the second cylinder 18 to tightly fix the double-opening lid, ensuring its stable position during transportation and capping;

[0042] The fiber optic sensor 9 is installed at the center of the bottom of the push plate 6. The detection light emitted by the fiber optic sensor 9 is emitted onto the positioning box 5 and then reflected back into the receiver in the fiber optic sensor 9. By detecting the intensity change of the reflected light, the presence and distance of the positioning box 5 are judged, and the position of the positioning box 5 is monitored in real time. When the positioning box 5 moves with the conveyor belt 4 into the detection range of the fiber optic sensor 9, the fiber optic sensor 9 sends a signal to the control box 20. After receiving the signal, the control box 20 judges that the positioning box 5 has reached the appropriate capping station, and then sends a start instruction to the first cylinder 11 and controls the conveyor belt 4 to stop working. The piston rod of the first cylinder 11 extends, pushing the push plate 6 to move downward. The guide rod 12 at the top of the push plate 6 slides in the vertical frame 10 to ensure the smooth movement of the push plate 6. The push plate 6 drives the two groups of capping heads 7 to move downward synchronously. The rubber block 8 at the bottom of the capping head 7 gradually approaches the double-opening lid. Since the rubber block 8 is slidably connected to the chute in the capping head 7 through a slider and a spring 13 is connected between the two, during the lid-closing process, the rubber block 8 can apply pressure evenly to achieve tight lid closing. A pressure sensor (not shown in the attached drawing) is installed in the capping head 7 to collect the pressure data during the capping process in real time and transmit the data to the control box 20. The control box 20 adjusts the output pressure of the first cylinder 11 precisely through an intelligent control algorithm according to the preset pressure threshold and the currently collected data, so that the pressure exerted by the rubber block 8 on the double-opening lid can not only ensure the tight combination of the lid and the container, but also will not damage the container. It can realize the capping operation on two groups of products at the same time, greatly improving the production efficiency;

[0043] After the capping head 7 completes the capping operation, the control box 20 sends a reverse instruction to the first cylinder 11. The piston rod of the first cylinder 11 retracts, driving the push plate 6 and the capping head 7 to reset upward and return to the initial position, waiting for the next capping operation. At the same time, the piston rod of the second cylinder 18 retracts, causing the arc-shaped block 15 to return to the initial position, releasing the double-opening lid that has been capped. The conveyor belt 4 continues to operate, conveying the products that have completed capping out and transporting the next group of double-opening lids to be capped to the capping station, and thus the capping operation is carried out in a cycle.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
