Description

Technical Field

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

[0002] In an existing filling and plugging system, a filling device and a plugging device are fixed on one side of a container conveying device. The filling device first fills the container, and then the plugging device plugs the filled container. Since the plugging process takes less time than 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 plugging device to finish plugging the first row of containers, thus affecting the production efficiency of the system. In addition, in some filling and plugging systems, both the filling device and the plugging device need to move in the container conveying direction, and the containers waiting for filling and plugging are also conveyed rhythmically during this process. In the filling and plugging processes, a motion mechanism is required for cooperation, and for the filling and plugging operations, precise positioning cooperation between the filling device, the plugging device and the container is needed. Therefore, during the filling and plugging operations of the container, positioning deviation is likely to occur, and the operation stability is difficult to guarantee. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

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

[0027] Figure 1 An embodiment of the plug-filling system of the present invention is shown. The plug-filling system of this embodiment includes a conveying device 1, a plug-feeding device 2, a filling device 3, a first plug-filling device 4, a second plug-filling device 5, and a rubber plug transfer device 6 for transferring the rubber plug 9 to the first plug-filling device 4 and the second plug-filling device 5. The filling device 3, the first plug-filling device 4, the second plug-filling device 5, the rubber plug transfer device 6, and the plug-feeding device 2 are arranged in sequence along the conveying device 1. The rubber plug transfer device 6 includes a mounting seat 61, a first swing arm 62 provided on the mounting seat 61, and a second swing arm 63 provided at the swing end of the first swing arm 62. A rubber plug positioning channel 64 is provided on the second swing arm 63, and a plug-pushing component 7 is provided below the plug-feeding device 2.

[0028] The filling and plugging system is provided with a first plugging device 4 and a second plugging device 5, and can select to plug two rows of containers 8 simultaneously to improve the plugging efficiency, thereby improving the production efficiency of the system. The rubber stopper transfer device 6 can accurately transfer the rubber stoppers 9 to the lower parts of 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. 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 containers 8, and ensures the stable operation of the system. Among them, the two swing arms preferably swing in the vertical plane, which is beneficial to reducing the area occupied by the system and avoiding interference with other components.

[0029] As a preferred technical solution, in this embodiment, since the rubber stopper transfer device 6 can accurately convey the rubber stoppers 9 to the lower parts of 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 containers 8.

[0030] 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 seat 34 can drive the filling needle 35 to reciprocate along the conveying device 1. When the plugging device plugs the containers 8, the filling device 3 can fill the subsequent other rows of containers 8, 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 containers 8.

[0031] The filling and plugging method of the high-speed filling and plugging system in this embodiment includes the following steps:

[0032] The rubber stopper transfer device 6 transfers the rubber stopper 9 to the lower part of the first plugging device 4: The swing end of the first swing arm 62 swings to the middle of the first plugging device 4 and the rubber stopper feeding device 2, the second swing arm 63 swings so that the rubber stopper positioning channel 64 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 64, and the second swing arm 63 swings so that the rubber stopper positioning channel 64 is located below the first plugging device 4;

[0033] The rubber stopper transfer device 6 transfers another rubber stopper 9 to the lower part of the second plugging device 5: The second swing arm 63 resets so that the rubber stopper positioning channel 64 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 64, the swing end of the first swing arm 62 swings to the middle of the second plugging device 5 and the rubber stopper feeding device 2, and the second swing arm 63 swings so that the rubber stopper positioning channel 64 is located below the second plugging device 5.

[0034] This plug-filling method can effectively and quickly transport the rubber stoppers 9 arranged continuously on the stopper feeding device 2 to the first plug-filling device 4 and the second plug-filling device 5, which is beneficial to improving the production efficiency of the system.

[0035] In this embodiment, the plug-filling method includes the following steps:

[0036] S1. The conveying device 1 conveys the container 8.

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

[0038] S3. The rubber stopper transfer device 6 transfers the rubber stopper 9 to the lower part of the first plug-filling device 4, and the first plug-filling device 4 plugs 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.

[0039] 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 the lower part of the first plug-filling device 4, and the first plug-filling device 4 plugs the first row of containers 8 in the next unit. The rubber stopper transfer device 6 transfers another rubber stopper 9 to the lower part of the second plug-filling device 5, and the second plug-filling device 5 plugs the last row of containers 8 in the current unit.

[0040] In this plug-filling 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 plug-filling device 4 plugs the first row of containers 8 in the next unit, and the second plug-filling device 5 plugs the last row of containers 8 in the current unit, which is beneficial to further improving the production efficiency of the system.
