Description

Technical Field

[0001] This invention relates to food and pharmaceutical packaging equipment and methods, and more particularly to systems and methods for container filling and capping. Background Technology

[0002] An existing system for container filling and capping involves a filling device and a capping device fixed to one side of a container conveying device. The filling device first fills the containers, and then the capping device caps the filled containers. Since the capping process takes less time than the filling process, when the filling device switches to filling the second row of containers after completing the first row, it must wait for the capping device to finish capping the first row, thus affecting the system's production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a system for container filling and capping that is simple in structure, has high production efficiency and good operational stability.

[0004] The present invention further provides the above-described method for filling and capping containers.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A system for container filling and capping includes a conveying device, a capping device, a filling device, a first capping device, a second capping device, and a cap transfer device for transferring caps to the first and second capping devices. The filling device, the first capping device, the second capping device, the cap transfer device, and the capping device are arranged sequentially along the conveying direction of the conveying device. The cap transfer device is a reciprocating structure and is provided with a first capping positioning channel corresponding to the first capping device and a second capping positioning channel corresponding to the second capping device. A capping component is provided below the capping device.

[0007] As a further improvement to the above technical solution: the top plug component includes a first top plug component corresponding to the first rubber plug positioning channel and a second top plug component corresponding to the second rubber plug positioning channel.

[0008] As a further improvement to the above technical solution: the filling device includes a first filling device and a second filling device.

[0009] As a further improvement to the above technical solution: the filling device includes a filling needle seat that can reciprocate along the conveying device and a filling needle disposed on the filling needle seat.

[0010] As a further improvement to the above technical solution: the first and second insert devices only move up and down.

[0011] A method for stoppering containers during filling includes the following steps:

[0012] S1, Conveying device for conveying containers;

[0013] S2. The filling device fills the containers;

[0014] S3. After the filling device completes filling of two or more rows of containers, the second stoppering device stops the containers in the previous row, while the first stoppering device stops the containers in the next row.

[0015] As a further improvement to the above technical solution: in step S2, the first filling device and the second filling device perform filling simultaneously.

[0016] As a further improvement to the above technical solution: In step S2, the filling device moves along the conveying device to fill each row of containers separately.

[0017] As a further improvement to the above technical solution, step S3 includes the following specific steps:

[0018] S3.1 The rubber stopper transfer device moves along the conveying device so that the first rubber stopper positioning channel and the second rubber stopper positioning channel are respectively aligned with the first top stopper component and the second top stopper component. The first top stopper component and the second top stopper component push the rubber stopper on the feeding device into the first rubber stopper positioning channel and the second rubber stopper positioning channel respectively.

[0019] S3.2 The rubber stopper transfer device moves along the conveying device to transfer the rubber stoppers in the first rubber stopper positioning channel and the second rubber stopper positioning channel to the bottom of the first stopper and the second stopper respectively;

[0020] S3.3 The first and second stopper devices press the lower rubber stopper into the container respectively.

[0021] Compared with the prior art, the advantages of the present invention are as follows: The system for container filling and capping disclosed in the present invention is provided with a first capping device and a second capping device, which can cap two rows of containers simultaneously to improve capping efficiency and thus improve the production efficiency of the system. The capping transfer device adopts a reciprocating moving structure and is provided with a first capping positioning channel and a second capping positioning channel. As the capping transfer device moves, the capping can be transferred from the top capping component below the capping device to the first capping positioning channel and the second capping positioning channel, which is convenient for the capping device to press into the container. Through the movement of the capping transfer device, the capping in the first capping positioning channel and the second capping positioning channel can be accurately transferred to the area below the first capping device and the second capping device. The filling device, the first capping device, and the second capping device in the system do not need to move along the conveying device. Only the conveying device drives the container to be conveyed intermittently, which is conducive to the accurate alignment of the filling device, each capping device and the container, and ensures the stable operation of the system.

[0022] The present invention discloses a method for stoppering containers during filling. After the filling device completes filling two or more rows of containers, a second stoppering device stops the first row of containers while the first stoppering device stops the second row of containers, which helps to improve the production efficiency of the system.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Figure 1 This illustration shows an embodiment of the system for container filling and capping according to the present invention. The system includes a conveying device 1, a capping device 2, a filling device 3, a first capping device 4, a second capping device 5, and a cap transfer device 6 for transferring caps 9 to the first and second capping devices 4 and 5. The filling device 3, the first capping device 4, the second capping device 5, the cap transfer device 6, and the capping device 2 are arranged sequentially along the conveying direction of the conveying device 1. The cap transfer device 6 is a reciprocating structure and has a first cap positioning channel 64 corresponding to the first capping device 4 and a second cap positioning channel 65 corresponding to the second capping device 5. A capping component 7 is provided below the capping device 2. Preferably, the capping component 7 can also reciprocate along the conveying device 1, providing greater flexibility and a wider range of applications.

[0029] This system for container filling and capping includes a first capping device 4 and a second capping device 5, which can simultaneously cap two rows of containers 8 to improve capping efficiency and thus increase the system's production efficiency. The capping transfer device 6 adopts a reciprocating moving structure and is equipped with a first capping positioning channel 64 and a second capping positioning channel 65. As the capping transfer device 6 moves, the capping 9 can be transferred from the top capping component 7 below the capping device 2 to the first capping positioning channel 64 and the second capping positioning channel 65, making it convenient for the capping device to press it into the container 8. Through the movement of the capping transfer device 6, the capping 9 in the first capping positioning channel 64 and the second capping positioning channel 65 can be accurately transferred to the area below the first capping device 4 and the second capping device 5. The filling device 3, the first capping device 4, and the second capping device 5 in the system do not need to move along the conveying device 1. Only the conveying device 1 drives the containers 8 to be conveyed intermittently or in a rhythmic manner, which is conducive to the accurate alignment of the filling device 3, each capping device, and the container 8, ensuring the stable operation of the system. The two swing arms preferably swing in a vertical plane, which helps to reduce the area occupied by the system and avoids interference with other components.

[0030] Furthermore, in this embodiment, the top plug component 7 includes a first top plug component 71 corresponding to the first rubber plug positioning channel 64 and a second top plug component 72 corresponding to the second rubber plug positioning channel 65. That is, after the rubber plug transfer device 6 moves into place, the rubber plug 9 is transferred to the first rubber plug positioning channel 64 and the second rubber plug positioning channel 65 respectively through the first top plug component 71 and the second top plug component 72. Compared with using only a single top plug component 7, the efficiency of the top plug process can be further improved.

[0031] Furthermore, in this embodiment, the filling device 3 includes a filling needle seat 34 that can reciprocate along the conveying device 1 and a filling needle 35 disposed on the filling needle seat 34. That is, the filling needle seat 34 can drive the filling needle 35 to reciprocate along the conveying device 1. When the stoppering device stops the container 8, the filling device 3 can fill other containers 8 in the subsequent process, which is beneficial to further improve the efficiency of the filling process. Of course, in other embodiments, the filling device 3 may only have the filling needle 35 moving up and down, while the filling needle seat 34 does not move, which is beneficial to ensure that the filling device 3 and the container 8 achieve precise positioning and cooperation.

[0032] As a preferred technical solution, in this embodiment, since the rubber stopper transfer device 6 can accurately transport the rubber stopper 9 to the bottom of the first stopper device 4 and the second stopper device 5, the first stopper device 4 and the second stopper device 5 only move up and down, without moving along the conveying device 1, which helps to ensure that the first stopper device 4 and the second stopper device 5 achieve precise positioning and cooperation with the container 8.

[0033] Example 2

[0034] Figure 2Another embodiment of the system for container filling and capping of the present invention is shown. The system for container filling and capping of this embodiment is basically the same as that of the first embodiment, except that: in this embodiment, the filling device 3 includes a first filling device 31 and a second filling device 32, that is, the filling is performed simultaneously by the first filling device 31 and the second filling device 32 to improve the efficiency of the filling process.

[0035] One embodiment of a method for stoppering a container for filling includes the following steps:

[0036] S1, conveying device 1 conveys container 8;

[0037] S2, The filling device 3 fills the container 8;

[0038] S3. After the filling device 3 has finished filling two or more rows of containers 8, the second stopper 5 stops the first row of containers 8, while the first stopper 4 stops the second row of containers 8.

[0039] In this capping method, after the filling device 3 has completed filling two or more rows of containers 8, the second capping device 5 caps the containers 8 in the previous row, while the first capping device 4 caps the containers 8 in the next row, which helps to improve the production efficiency of the system.

[0040] As a preferred technical solution, in this embodiment, in step S2, the first filling device 31 and the second filling device 32 perform filling simultaneously to improve the efficiency of the filling process. Alternatively, in other embodiments, in step S2, the filling device 3 moves along the conveying device 1 to fill each row of containers 8 separately to improve the efficiency of the filling process.

[0041] Furthermore, in this embodiment, step S3 specifically includes the following steps:

[0042] S3.1 The rubber stopper transfer device 6 moves along the conveying device 1 so that the first rubber stopper positioning channel 64 and the second rubber stopper positioning channel 65 are respectively aligned with the first top stopper component 71 and the second top stopper component 72. The first top stopper component 71 and the second top stopper component 72 push the rubber stopper 9 on the feeding device 2 into the first rubber stopper positioning channel 64 and the second rubber stopper positioning channel 65 respectively. Compared with using only a single top stopper component 7, the distance that the rubber stopper transfer device 6 moves can be reduced, and the efficiency of the top stopper process can be further improved.

[0043] S3.2, The rubber stopper transfer device 6 moves along the conveying device 1 to transfer the rubber stoppers 9 in the first rubber stopper positioning channel 64 and the second rubber stopper positioning channel 65 to the bottom of the first stoppering device 4 and the second stoppering device 5 respectively;

[0044] S3.3, the first stopper 4 and the second stopper 5 respectively press the lower rubber stopper 9 into the container 8. After that, the rubber stopper transfer device 6 is reset, ready for the next transfer. The structure is simple, reliable and has high transfer efficiency.

[0045] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
