Description

Technical Field

[0001] The invention mainly relates to the field of food and pharmaceutical packaging, and in particular to a capping machine and method with a vacuum plugging mechanism. Background Art

[0002] In the existing stoppering and capping machines, the vacuuming and stoppering are located at the same station, that is, when the bottle body reaches the vacuuming station, the stopper head first removes the stopper, then vacuumizes and nitrogenizes the bottle body, and then the stopper head presses the stopper into the bottle mouth. During the process of removing the stopper and pressing the stopper, friction will produce particles, which is easy to cause pollution to the medicine; and this structure is only suitable for larger bottles with a smaller bottle mouth than the bottle body, that is, the stopper head can quickly align to the bottle mouth and perform stoppering, and the process will not cause the stopper head to damage the bottle mouth. However, when it comes to small-sized bottles with a bottle mouth larger than the bottle body, it is difficult for the stopper head to accurately align to the bottle mouth. Once there is a deviation in the alignment, the stopper head cannot quickly press the stopper, and on the other hand, it will cause the bottle mouth to be damaged. Summary of the invention

[0009] A bottle clamping cavity is arranged at the bottom of the vacuum sealing sleeve, a sealing ring tightly attached to the bottle body is arranged at the bottom of the bottle clamping cavity, and an air nozzle communicating with the bottle clamping cavity is arranged at the bottom of the vacuum sealing sleeve.

[0010] The first lifting assembly includes a first driving member and a first lifting rod. The first driving member is installed on the support frame. One end of the first lifting rod is connected to the output end of the first driving member, and the other end is connected to the vacuum sealing sleeve.

[0011] The second lifting assembly includes a second driving member and a second lifting rod. The second driving member is installed on the support frame. One end of the second lifting rod is connected to the output end of the second driving member, and the other end extends into the vacuum sealing sleeve.

[0013] The capping mechanism comprises a capping feeder and a capping member, wherein the capping feeder is connected to the middle conveying path, and the capping member is arranged on the upper part of the middle conveying path and is located behind the capping feeder.

[0014] A sampling dial wheel is arranged at the butt joint between the middle conveying path and the bottle discharging conveying path.

[0015] A plugging and capping method is performed using the above-mentioned capping machine with a vacuum plugging mechanism, comprising the following steps:

[0016] S1: Bottle feeding: Bottles are fed into the bottle feeding channel;

[0017] S2: Half-stoppering: When the bottle reaches the position of the half-stoppering mechanism, the half-stoppering mechanism performs a half-stoppering action on the bottle;

[0018] S3: Vacuuming and plugging: When the bottle body is transported from the middle conveying channel to the position of the vacuuming and plugging mechanism, the vacuum plugging mechanism performs a vacuuming action on the bottle body and realizes the subsequent full plugging action;

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figures 1 to 5 An embodiment of a capping machine with a vacuum plugging mechanism of the present invention is shown, comprising a frame 1, the frame 1 is provided with a bottle inlet conveyor 2, an intermediate conveyor 3 and a bottle outlet conveyor 4 in sequence, the intermediate conveyor 3 and the bottle outlet conveyor 4 are butted, a semi-plugging mechanism 5 is butted between the bottle inlet conveyor 2 and the intermediate conveyor 3, a vacuum plugging mechanism 6 and a capping mechanism 7 are provided in sequence on the intermediate conveyor 3, and the vacuum plugging mechanism 6 is located behind the semi-plugging mechanism 5. When the plugging and capping machine is in operation, the bottle body enters from the bottle inlet conveyor 2, when the bottle body is conveyed to the position of the semi-plugging mechanism 5, the semi-plugging mechanism 5 performs a semi-plugging action on the bottle body, and then the bottle body is conveyed to the intermediate conveyor 3, when the bottle body is conveyed to the position of the vacuum plugging mechanism 6, the vacuum plugging mechanism 6 performs a vacuum action on the bottle body and realizes the subsequent full plugging action, and then the bottle body is conveyed to the position of the capping mechanism 7, and the capping mechanism 7 performs a capping action on the bottle body, and finally the bottle body is output from the bottle outlet conveyor 4 to the next process. Compared with the traditional structure, the plugging and capping machine separates the entire plugging process. When the semi-plugging mechanism 5 completes the first half of the plugging action and the semi-plugged bottle is in the position of the vacuum plugging mechanism 6, the vacuum plugging mechanism 6 can directly evacuate the semi-plugged bottle, and then perform the full plugging action, that is, there is no plugging action at the vacuum station, which prevents contamination. When it comes to small-sized bottles, it only needs to lower the vacuum plugging mechanism 6 to seal the bottle body. There is no problem of plugging and alignment, and there is no problem of damaging the bottle mouth during alignment. The structure is simple and ingenious.

[0033] In this embodiment, the semi-stoppering mechanism 5 includes a stoppering hopper 51, a lifting bottom rail 52, a stoppering dial wheel 53 and a stoppering suction cup 54. The stoppering hopper 51 is installed on the frame 1 and docked with the stoppering suction cup 54. The lifting bottom rail 52 is installed on the frame 1 and supported on the bottom of the stoppering dial wheel 53. The stoppering suction cup 54 is arranged above the stoppering dial wheel 53 and rotates synchronously with the stoppering dial wheel 53. The stoppering dial wheel 53 is docked with the bottle inlet conveying path 2 and the intermediate conveying path 3. In this structure, the bottle stoppers enter the stoppering suction cups 54 from the stopper sorting hopper 51 and are adsorbed on the suction cups 54 in order. The stoppering dial 53 drives the bottle body to rotate through its teeth, and the stoppering suction cups 54 rotate synchronously with the stoppering dial 53, so that the bottle stoppers are always located directly above the bottle mouths of the corresponding bottles. The lifting bottom rail 52 under the bottle body drives the bottle body to rise and fall. When the bottle body moves from a low point to a high point, the distance between the bottle stopper and the bottle mouth of the bottle body becomes smaller, and the bottle stopper is gradually inserted into the bottle mouth. At the highest point, the stoppering suction cup 54 releases the vacuum, and the bottle stopper is separated from the stoppering suction cup 54, completing semi-stoppering.

[0034] In this embodiment, the vacuum plugging mechanism 6 includes a support frame 61, a first lifting assembly 62, a second lifting assembly 63 and a vacuum sealing sleeve 64. The support frame 61 is installed on the frame 1, and the first lifting assembly 62 and the second lifting assembly 63 are both installed on the frame 1. The vacuum sealing sleeve 64 is installed at the output end of the first lifting assembly 62, and the vacuum sealing sleeve 64 is located above the intermediate conveying path 3 corresponding to the position of the bottle body, and the output end of the second lifting assembly 63 is located in the vacuum sealing sleeve 64. In this structure, the half-stoppered bottle body is transported to the vacuum station by the intermediate conveying path 3. At this time, the first lifting assembly 62 drives the vacuum sealing sleeve 64 to descend, and the vacuum sealing sleeve 64 squeezes the bottle body to form a seal. The vacuum solenoid valve is opened to vacuumize the bottle body. After vacuuming, the second lifting assembly 63 descends, presses the bottle plug into the bottle, completes the full stoppering, and then the vacuum sealing sleeve 64 rises, and the second lifting assembly 63 rises to wait for the next batch of half-stoppered bottles. In this embodiment, the bottle body is also filled with nitrogen after vacuuming.

[0035] In this embodiment, a bottle clamping cavity 641 is provided at the bottom of the vacuum sealing sleeve 64, a sealing ring 6411 is provided at the bottom of the bottle clamping cavity 641, and a gas nozzle 642 is provided at the bottom of the vacuum sealing sleeve 64, which is in communication with the bottle clamping cavity 641. In this structure, the half-stoppered bottle body is transported to the vacuum station by the middle conveying path 3, at which time, the first lifting assembly 62 drives the vacuum sealing sleeve 64 to descend, and its bottle clamping cavity 641 squeezes the bottle body to form a seal, and the vacuum solenoid valve is opened, and the gas nozzle 642 vacuums the bottle body through the bottle clamping cavity 641.

[0036] In this embodiment, the first lifting assembly 62 includes a first driving member 621 and a first lifting rod 622. The first driving member 621 is installed on the support frame 61. One end of the first lifting rod 622 is connected to the output end of the first driving member 621, and the other end is connected to the vacuum sealing sleeve 64. In this structure, the first driving member 621 is a cylinder, which drives the first lifting rod 622 to rise and fall, thereby driving the vacuum sealing sleeve 64 to rise and fall.

[0037] In this embodiment, the second lifting assembly 63 includes a second driving member 631 and a second lifting rod 632. The second driving member 631 is installed on the support frame 61. One end of the second lifting rod 632 is connected to the output end of the second driving member 631, and the other end extends into the vacuum sealing sleeve 64. In this structure, the second driving member 631 is a cylinder, which drives the second lifting rod 632 to move up and down. When the second lifting rod 632 descends from a high position to a low position, it applies force to the bottle stopper of the half-stoppered bottle body to complete the full stoppering action.

[0038] In this embodiment, a positioning pad 6321 for abutting against the bottle stopper is provided at the bottom of the second lifting rod 632. The positioning pad 6321 is sleeved on the upper part of the bottle stopper and abuts against it. On the one hand, it plays a quick positioning effect when pressing down to improve the pressing effect, and on the other hand, it plays a buffering role for the bottle stopper, avoiding the second lifting rod 632 from rigidly contacting the bottle stopper, and effectively protecting the bottle stopper.

[0039] In this embodiment, the capping mechanism 7 includes a capping feeder 71 and a capping member 72. The capping feeder 71 is connected to the intermediate conveying path 3, and the capping member 72 is arranged on the upper part of the intermediate conveying path 3 and behind the capping feeder 71. In this structure, the bottle caps enter the bottle mouths of the corresponding bottles on the intermediate conveying path 3 from the capping feeder 71, and are continuously conveyed from the intermediate conveying path 3 to the position of the capping member 72, and the capping member 72 is actuated to complete the capping action.

[0040] In this embodiment, a sampling wheel 8 is provided at the docking position of the middle conveying path 3 and the bottle discharging conveying path 4. In this structure, the sampling wheel 8 performs sampling and detection on the bottle body to ensure the quality of the plugging and capping.

[0041] Figures 1 to 6 An embodiment of the plugging and capping method of the present invention is shown, which is performed using the above-mentioned capping machine with a vacuum plugging mechanism, and includes the following steps:

[0042] S1: Bottle feeding: Bottles are fed in through bottle feeding conveyor 2;

[0043] S2: Half-stoppering: When the bottle reaches the position of the half-stoppering mechanism 5, the half-stoppering mechanism 5 performs a half-stoppering action on the bottle;

[0044] S3: Vacuuming and plugging: When the bottle body is transported from the middle conveying channel 3 to the position of the vacuuming and plugging mechanism 6, the vacuuming and plugging mechanism 6 performs a vacuuming action on the bottle body and realizes the subsequent full plugging action;

[0045] S4: capping: the bottle body is transported from the middle conveying path 3 to the position of the capping mechanism 7, and the capping mechanism 7 performs capping on the bottle body;

[0046] S5: Bottle discharging: The bottle body after capping is discharged to the next process through the bottle discharging conveyor 4.

[0047] By adopting this method, the plugging and capping machine can separate the entire plugging process. When the semi-plugging mechanism 5 completes the first half of the plugging action and the semi-plugged bottle is at the position of the vacuum plugging mechanism 6, the vacuum plugging mechanism 6 can directly evacuate the semi-plugged bottle, and then perform the full plugging action, that is, there is no plugging removal action at the vacuum station, thereby preventing contamination. When it comes to small-sized bottles, it only needs to lower the vacuum plugging mechanism 6 to seal the bottle body. There is no problem of plugging removal alignment, and there is no problem of damaging the bottle mouth during alignment. The structure is simple and ingenious.
