Description

Technical Field

[0001] The present invention relates to food and drug packaging equipment and methods, and particularly to a filling and stoppering system and method. Background Art

[0002] In an existing filling and stoppering system, the filling device and the stoppering device are fixed on one side of the container conveying device. The filling device first fills the container, and then the stoppering device stoppers the filled container. Since the time required for the stoppering process is shorter than that of the filling process, after the filling device finishes filling the first row of containers and switches to filling the second row of containers, it is necessary to wait for the stoppering device to finish stoppering the first row of containers, thus affecting the production efficiency of the system. In addition, in some filling and stoppering systems, both the filling device and the stoppering device need to move in the container conveying direction, and the containers waiting for filling and stoppering are also conveyed rhythmically during this process. In the filling and stoppering processes, a motion mechanism is required for cooperation, and for the filling and stoppering operations, precise positioning cooperation between the filling device, the stoppering device and the container is needed. Therefore, it is easy to have positioning deviation during the filling and stoppering operations of the container, and it is difficult to ensure the running stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a filling and stoppering system with a simple structure, high production efficiency and good running stability.

[0004] The present invention further provides a filling and stoppering method for the above filling and stoppering system.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A filling and stoppering system includes a conveying device, a plug feeding device, a filling device, a first stoppering device, a second stoppering device, and a rubber plug transfer device for transferring rubber plugs to the first stoppering device and the second stoppering device. The filling device, the first stoppering device, the second stoppering device, the rubber plug transfer device and the plug feeding device are arranged in sequence along the conveying direction of the conveying device. The rubber plug transfer device includes a mounting seat that can reciprocate along the conveying device and a swing arm provided on the mounting seat. The swing arm is provided with a rubber plug positioning channel, and a plug pushing member is provided below the plug feeding device.

[0007] As a further improvement of the above technical solution: The first stoppering device and the second stoppering device only perform lifting motion.

[0008] As a further improvement of the above technical solution: The filling device includes a filling needle seat that can reciprocate along the conveying device and a filling needle provided on the filling needle seat.

[0009] A filling and stoppering method for the above filling and stoppering system includes steps:

[0010] The rubber stopper transfer device transfers the rubber stopper to below the first stopper adding device: The mounting seat moves to the middle of the first stopper adding device and the stopper feeding device. The swing arm swings to make the rubber stopper positioning channel above the stopper pushing component. The stopper pushing component pushes the rubber stopper on the stopper feeding device into the rubber stopper positioning channel. The swing arm swings to make the rubber stopper positioning channel below the first stopper adding device;

[0011] The rubber stopper transfer device transfers another rubber stopper to below the second stopper adding device: The swing arm resets to make the rubber stopper positioning channel above the stopper pushing component. The stopper pushing component pushes the rubber stopper on the stopper feeding device into the rubber stopper positioning channel. The mounting seat moves to the middle of the second stopper adding device and the stopper feeding device. The swing arm swings to make the rubber stopper positioning channel below the second stopper adding device.

[0012] As a further improvement of the above technical solution:

[0013] The filling and stopper adding method includes the steps:

[0014] S1. The conveying device conveys the containers;

[0015] S2. The filling device fills the containers;

[0016] S3. The rubber stopper transfer device transfers the rubber stopper to below the first stopper adding device. The first stopper adding device adds a stopper to the container. Steps S1 to S3 are repeatedly executed until the filling of the last row of containers in the current unit is completed;

[0017] S4. After the filling of the last row of containers in the current unit is completed, the filling device fills the first row of containers in the next unit. The rubber stopper transfer device transfers the rubber stopper to below the first stopper adding device. The first stopper adding device adds a stopper to the first row of containers in the next unit. The rubber stopper transfer device transfers another rubber stopper to below the second stopper adding device. The second stopper adding device adds a stopper to the last row of containers in the current unit.

[0018] Compared with the prior art, the advantages of the present invention are as follows: The filling and stopper adding system disclosed by the present invention is provided with a first stopper adding device and a second stopper adding device, and can select to add stoppers to two rows of containers at the same time at a certain moment to improve the stopper adding efficiency, and further improve the production efficiency of the system. The rubber stopper transfer device includes a mounting seat that can reciprocate along the conveying device and a swing arm provided on the mounting seat. A rubber stopper positioning channel is provided on the swing arm. The rubber stopper can be transferred from the stopper pushing component below the stopper feeding device into the rubber stopper positioning channel, which is convenient for the stopper adding device to press it into the container later. Through the movement of the mounting seat and the swing of the swing arm, the rubber stopper can be accurately transferred to below the first stopper adding device and the second stopper adding device. The filling device, the first stopper adding device, and the second stopper adding device in the system do not need to move along the conveying device, and only the conveying device drives the containers to be intermittently conveyed, which is beneficial to the accurate alignment of the filling device, each stopper adding device and the containers, and ensures the stable operation of the system.

Detailed Embodiments

[0025] The present invention will be further described in detail below with reference to the drawings in the specification and specific embodiments.

[0026] Figures 1 to 4 An embodiment of the filling and plugging system of the present invention is shown. The filling and plugging system of this embodiment includes a conveying device 1, a rubber stopper feeding device 2, a filling device 3, a first plugging device 4, a second plugging device 5, and a rubber stopper transfer device 6 for transferring the rubber stopper 9 to the first plugging device 4 and the second plugging device 5. The filling device 3, the first plugging device 4, the second plugging device 5, the rubber stopper transfer device 6, and the rubber stopper feeding device 2 are arranged in sequence along the conveying direction of the conveying device 1. The rubber stopper transfer device 6 includes a mounting seat 61 that can reciprocate along the conveying device 1 and a swing arm 62 provided on the mounting seat 61. A rubber stopper positioning channel 63 is provided on the swing arm 62. A plugging component 7 is provided below the rubber stopper feeding device 2.

[0027] The filling and plugging system is provided with a first plugging device 4 and a second plugging device 5, and can choose to plug two rows of containers 8 simultaneously at a certain moment to improve the plugging efficiency, thereby improving the production efficiency of the system. The rubber stopper transfer device 6 includes a mounting seat 61 that can reciprocate along the conveying device 1 and a swing arm 62 provided on the mounting seat 61. A rubber stopper positioning channel 63 is provided on the swing arm 62. The rubber stopper 9 can be transferred from the plugging member 7 below the rubber stopper feeding device 2 into the rubber stopper positioning channel 63, which is convenient for being pressed into the container 8 by the plugging device later. Through the movement of the mounting seat 61 and the swing of the swing arm 62, the rubber stopper 9 can be accurately transferred below the first plugging device 4 and the second plugging device 5. The filling device 3, the first plugging device 4, and the second plugging device 5 in the system do not need to move along the conveying device 1, and only the conveying device 1 drives the containers 8 to be intermittently or rhythmically conveyed, which is beneficial to the accurate alignment of the filling device 3, each plugging device and the container 8, and ensures the stable operation of the system. Among them, the swing arm 62 preferably swings in the vertical plane, which is beneficial to reducing the area occupied by the system and avoiding interference with other components.

[0028] As a preferred technical solution, in this embodiment, since the rubber stopper transfer device 6 can accurately convey the rubber stopper 9 below the first plugging device 4 and the second plugging device 5, the first plugging device 4 and the second plugging device 5 only perform lifting movements and do not need to move along the conveying device 1, which is beneficial to ensuring the precise positioning and cooperation between the first plugging device 4 and the second plugging device 5 and the container 8.

[0029] As a preferred technical solution, 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 provided on the filling needle seat 34, that is, the filling needle 35 can be driven by the filling needle seat 34 to reciprocate along the conveying device 1. When the plugging device plugs the container 8, the filling device 3 can fill other rows of containers 8 subsequently, which is beneficial to further improving the production efficiency of the system. Of course, in other embodiments, the filling device 3 can also only have the filling needle 35 perform lifting movements and the filling needle seat 34 does not move, which is beneficial to ensuring the precise positioning and cooperation between the filling device 3 and the container 8.

[0030] The filling and plugging method of the filling and plugging system in this embodiment includes the following steps:

[0031] The rubber stopper transfer device 6 transfers the rubber stopper 9 below the first plugging device 4: the mounting seat 61 moves to the middle of the first plugging device 4 and the rubber stopper feeding device 2, the swing arm 62 swings so that the rubber stopper positioning channel 63 is located above the plugging member 7, the plugging member 7 pushes the rubber stopper 9 on the rubber stopper feeding device 2 into the rubber stopper positioning channel 63, and the swing arm 62 swings so that the rubber stopper positioning channel 63 is located below the first plugging device 4;

[0032] The rubber stopper transfer device 6 transfers another rubber stopper 9 to below the second stopper adding device 5: The swing arm 62 resets to make the rubber stopper positioning channel 63 located above the stopper pushing component 7, and the stopper pushing component 7 pushes the rubber stopper 9 on the stopper feeding device 2 into the rubber stopper positioning channel 63. The mounting seat 61 moves to the middle of the second stopper adding device 5 and the stopper feeding device 2, and the swing arm 62 swings to make the rubber stopper positioning channel 63 located below the second stopper adding device 5.

[0033] This filling and stopper adding method can quickly and accurately transfer the rubber stopper 9 to below the first stopper adding device 4 and the second stopper adding device 5, which is beneficial to improving the production efficiency of the system.

[0034] In this embodiment, the filling and stopper adding method includes the steps:

[0035] S1. The conveying device 1 conveys the container 8.

[0036] S2. The filling device 3 fills the container 8.

[0037] S3. The rubber stopper transfer device 6 transfers the rubber stopper 9 to below the first stopper adding device 4, and the first stopper adding device 4 adds a stopper to the container 8. Steps S1 to S3 are repeatedly executed until the filling of the last row of containers 8 in the current unit is completed.

[0038] S4. After the filling of the last row of containers 8 in the current unit is completed, the filling device 3 fills the first row of containers 8 in the next unit, the rubber stopper transfer device 6 transfers the rubber stopper 9 to below the first stopper adding device 4, the first stopper adding device 4 adds a stopper to the first row of containers 8 in the next unit, the rubber stopper transfer device 6 transfers another rubber stopper 9 to below the second stopper adding device 5, and the second stopper adding device 5 adds a stopper to the last row of containers 8 in the current unit.

[0039] In this filling and stopper adding method, after the filling of the last row of containers 8 in the current unit is completed, the filling device 3 fills the first row of containers 8 in the next unit, the first stopper adding device 4 adds a stopper to the first row of containers 8 in the next unit, and the second stopper adding device 5 adds a stopper to the last row of containers 8 in the current unit, which is beneficial to improving the production efficiency of the system.
