Description

Technical Field

[0001] The invention relates to food and medicine packaging equipment, in particular to a rubber plug transport device. 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 completes the filling of the first row of containers, when it switches to the second row of containers for filling, it is necessary to wait for the plugging device to complete plugging the first row of containers, thereby affecting the production efficiency of the system. In addition, in some filling and plugging systems, the filling device and the plugging device need to move in the direction of container transmission, and the containers waiting for filling and plugging are also transported rhythmically during this process. The motion mechanism needs to cooperate in the filling and plugging processes, and the filling and plugging operations require precise positioning and coordination of the filling device, the plugging device and the container. Therefore, positioning deviations are prone to occur during the filling and plugging operations of the containers, and operational stability is difficult to guarantee. Summary of the invention

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Embodiment 1

[0040] Figures 1 to 6An embodiment of the system for high-speed filling and plugging of the present invention is shown. The system for high-speed filling and plugging of this embodiment comprises a conveying device 1, a plugging device 2, a filling device 3, a first plugging device 4, a second plugging device 5, and a plug transfer device 6 for transferring the plug 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 plug transfer device 6 and the plug feeding device 2 are arranged in sequence along the conveying direction of the conveying device 1. The plug transfer device 6 comprises a first plugging plate 61 provided with a first plug positioning channel 63, a second plugging plate 62 provided with a second plug positioning channel 66, and an eccentric shaft assembly for driving the first plugging plate 61 and the second plugging plate 62 to rotate to adjust the distance between the first plug positioning channel 63 and the second plug positioning channel 66. The first plug positioning channel 63 corresponds to the first plugging device 4, and the second plug positioning channel 66 corresponds to the second plugging device 5. A top plug component 7 is provided below the plug feeding device 2.

[0041] 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 at the same time to improve the plugging efficiency, thereby improving the production efficiency of the system. The plug transfer device 6 can quickly and accurately transfer the two rows of plugs 9 from the plug feeding device 2 to the bottom of the first plugging device and the second plugging device 5 at the same time. 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 container 8 to be transported intermittently or rhythmically, 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.

[0042] Further, in the present embodiment, the eccentric shaft assembly includes an eccentrically arranged first rotating shaft 64 and a second rotating shaft 65, the first rotating shaft 64 is connected to the first plugging plate 61, the second rotating shaft 65 is connected to the second plugging plate 62, the first rotating shaft 64 is a hollow shaft, and the second rotating shaft 65 is arranged in the first rotating shaft 64. The first rotating shaft 64 drives the first plugging plate 61 to rotate, and the second rotating shaft 65 drives the second plugging plate 62 to rotate. Since the two rotating shafts are eccentrically arranged, the distance between the first rubber plug positioning channel 63 and the second rubber plug positioning channel 66 will periodically increase or decrease. When the first rubber plug positioning channel 63 and the second rubber plug positioning channel 66 are close to each other, it is convenient to plug. When separated, the first plugging device 4 and the second plugging device 5 can be plugged. The overall structure of this eccentric shaft assembly is compact and takes up little space. Of course, in other embodiments, the second rotating shaft 65 can also be a hollow shaft, and the first rotating shaft 64 can be arranged in the second rotating shaft 65, which can also achieve the purpose of the invention.

[0043] Furthermore, in this embodiment, the plug transport device 6 also includes a driving shaft 60, and a first connecting rod 68 is provided on both the driving shaft 60 and the second rotating shaft 65. The first connecting rod 69 is hinged at both ends of the first connecting rod 68 on the driving shaft 60. The ends of the second connecting rod 69, the ends of the first connecting rod 68 on the second rotating shaft 65, and the first rotating shaft 64 are hinged, and the two first connecting rods 68 and the two second connecting rods 69 constitute a parallelogram linkage mechanism. The eccentrically arranged first rotating shaft 64 and the second rotating shaft 65 can be synchronously rotated by a driving shaft 60 and a parallelogram linkage mechanism, which is conducive to reducing the number of driving components, simplifying the structure, and reducing costs. Of course, in other embodiments, if the second rotating shaft 65 is a hollow shaft, the first rotating shaft 64 is arranged in the second rotating shaft 65, and accordingly, the driving shaft 60 and the first rotating shaft 64 are both provided with a first connecting rod 68, and the first connecting rod 68 on the driving shaft 60 is hinged at both ends with a second connecting rod 69, and the end of the second connecting rod 69, the end of the first connecting rod 68 on the first rotating shaft 64 and the second rotating shaft 65 are hinged, and the two first connecting rods 68 and the two second connecting rods 69 constitute a parallelogram connecting rod mechanism, which can also achieve the purpose of the invention.

[0044] Furthermore, in this embodiment, a connecting pin 611 is provided between the first plugging plate 61 and the second plugging plate 62, and an elastic member 612 is sleeved on the connecting pin 611, and both ends of the elastic member 612 are respectively against the first plugging plate 61 and the second plugging plate 62. Since only one set of rotation drive components is provided, the connecting pin 611 is provided to facilitate the transmission of the rotation drive force between the first plugging plate 61 and the second plugging plate 62, and the elastic member 612 is sleeved on the connecting pin 611 to achieve a flexible connection between the first plugging plate 61 and the second plugging plate 62, thereby ensuring the stability and smoothness of the rotation movement, and the simple and reliable structure.

[0045] Furthermore, in this embodiment, the plugging component 7 includes a first plugging component 71 corresponding to the first rubber plug positioning channel 63, and a second plugging component 72 corresponding to the second rubber plug positioning channel 66. The first plugging component 71 and the second plugging component 72 are plugged at the same time, which is conducive to speeding up the plugging process and further improving the efficiency.

[0046] As a preferred technical solution, in this embodiment, since the stopper transfer device 6 can accurately transport the stopper 9 to the bottom of the first stoppering device 4 and the second stoppering device 5, the first stoppering device 4 and the second stoppering device 5 only move up and down without moving along the conveying device 1, which is beneficial to ensure that the first stoppering device 4 and the second stoppering device 5 are accurately positioned and matched with the container 8.

[0047] 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 arranged 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 container 8, the filling device 3 can fill other rows of containers 8, which is conducive to further improving the production efficiency of the system. Of course, in other embodiments, the filling device 3 can also only move the filling needle 35 up and down, and the filling needle seat 34 does not move, which is conducive to ensuring that the filling device 3 and the container 8 are accurately positioned and matched.

[0048] Embodiment 2

[0049] Figures 7 and 8 Another embodiment of the system for high-speed filling and plugging of the present invention is shown. This embodiment is basically the same as the first embodiment, except that: in this embodiment, the first rotating shaft 64 is arranged on a sliding mechanism 67, that is, the eccentricity between the first rotating shaft 64 and the second rotating shaft 65 can be adjusted by the sliding mechanism 67 to adapt to the filling and plugging of containers of different specifications. The disadvantage is that it leads to an increase in the volume of the equipment and an increase in the occupied plant area. Of course, in other embodiments, the second rotating shaft 65 can also be arranged on a sliding mechanism 67, or the first rotating shaft 64 and the second rotating shaft 65 can be arranged on a sliding mechanism 67 respectively.

[0050] The filling and plugging method of the filling and plugging system of this embodiment comprises the following steps:

[0051] S1, the conveying device 1 conveys the container 8;

[0052] S2, the filling device 3 fills the container 8;

[0053] S3, after the filling device 3 completes filling of more than two rows of containers 8, the second plugging device 5 plugs the containers 8 in the previous row, and the first plugging device 4 plugs the containers 8 in the next row.

[0054] In the filling and plugging method, after the filling device 3 completes filling of more than two rows of containers 8, the second plugging device 5 plugs the containers 8 in the previous row, and the first plugging device 4 plugs the containers 8 in the next row, which is beneficial to improving the production efficiency of the system.

[0055] Furthermore, in this embodiment, in step S2, the filling needle seat 34 drives the filling needle 35 to move back and forth along the conveying device 1 to fill the subsequent other rows of containers 8, which is beneficial to further improve the production efficiency of the system.

[0056] Furthermore, in this embodiment, the specific steps of step S3 include:

[0057] S3.1. The first rotating shaft 64 drives the first plugging plate 61 to rotate so that the first rubber plug positioning channel 63 moves to above the first plugging component 71. The second rotating shaft 65 drives the second plugging plate 62 to rotate so that the second rubber plug positioning channel 66 moves to above the second plugging component 72. At this time, the first rubber plug positioning channel 63 and the second rubber plug positioning channel 66 are close to each other.

[0058] S3.2, the first plugging component 71 pushes one rubber plug 9 into the first rubber plug positioning channel 63, and the second plugging component 72 pushes another rubber plug 9 into the second rubber plug positioning channel 66;

[0059] S3.3, the first rotating shaft 64 drives the first plugging plate 61 to rotate so that the first rubber plug positioning channel 63 moves to below the first plugging device 4, and the second rotating shaft 65 drives the second plugging plate 62 to rotate so that the second rubber plug positioning channel 66 moves to below the second plugging device 5, at which time the first rubber plug positioning channel 63 and the second rubber plug positioning channel 66 are separated;

[0060] S3.4, the first plugging device 4 and the second plugging device 5 respectively press the rubber plugs 9 below into the container 8. This step has a high degree of automation, and can quickly and accurately transfer two rows of rubber plugs 9 to the bottom of the first plugging device 4 and the second plugging device 5 at the same time, and the first plugging component 71 and the second plugging component 72 only need to move up and down without moving along the conveying device 1, which is conducive to improving the efficiency of the rubber plugs 9 entering the rubber plug positioning channel.
