Description

Technical Field

[0001] The present invention relates to the technical field of filling equipment, and particularly relates to a filling equipment for multi-cavity containers. Background Art

[0002] In the field of packaging machinery, filling equipment is the core device for achieving precise filling of materials. Its development has experienced a transformation from manual to automated and intelligent, and it is widely used in fields such as food and medicine.

[0003] With the diversification of market demands (such as the demands for product diversification, personalization, and multi-functionality in the pharmaceutical, cosmetic, and food industries), multi-cavity containers have emerged. The multi-cavity design can integrate multiple independent cavities, and different materials or different doses of the same material can be filled simultaneously, significantly improving production efficiency and product consistency.

[0004] However, the existing rotary filling equipment can only fill single-cavity packaging cavities during use. When sealing multi-cavity products, additional filling stations need to be added, and multiple cavities cannot be filled simultaneously, greatly reducing production efficiency.

[0005] Due to the rotation of the packaging container during transportation and conveyance, there is a positional deviation between the multiple storage cavities in the packaging container and the material passing channels of the cups. To ensure the filling effect, the geometric symmetry requirements between the multi-cavity container and the cups are extremely high. Therefore, the vertical alignment between the cups and the cavities requires accurate control of position and angle during filling. If manual alignment is used, it has low efficiency, insufficient accuracy, and is prone to errors.

[0006] In response to this, the prior art uses a multi-nozzle structure based on matrix arrangement and a step-by-step positioning system to position the multi-cavity container for synchronous filling, and cooperates with a vision detection device for position calibration. However, the above methods have problems such as complex structure, high cost, and low production efficiency.

[0007] At the same time, the cups in the existing rotary filling device are directly fixedly connected to the turntable. During the filling process of the packaging container, to ensure complete filling, the packaging container generally needs to move vertically. At this time, the packaging container will intermittently impact the cups, causing the cups to swing up and down, resulting in an offset between the material passing channels and the cavities, affecting the filling effect and reducing the service life of the cups. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a filling equipment for multi-cavity containers to achieve filling / dosing different materials into corresponding different cavities in a single container.

A second guiding channel 85 is formed between the top of the first guiding ring 81 within the descending section and the second arc-shaped convex part 821. The lifting connection module 67 moves circumferentially along the first guiding channel 84 and the second guiding channel 85.

[0100] The end of the first arc-shaped convex part 811 adjacent to the end of the second guiding channel 85 is arranged as an inclined surface. The lower end of the inclined surface is connected to the top of the first guiding ring 81. The lifting connection module 67 is guided from the second guiding channel 85 to the first guiding channel 84 through the inclined surface.

[0101] The head and tail ends of the second arc-shaped convex part 821 are in an inclined transition with the bottom of the second guiding ring 82, thereby playing a guiding role.

[0102] The movable supporting block 83 is driven by a supporting block driving source and is arranged to be liftable at the starting end of the second guiding channel 85. In this embodiment, the supporting block driving source is a cylinder. Specifically, the movable supporting block 83 is opposite to the guiding and positioning device 7 front and back.

[0103] The supporting block driving source is fixedly arranged at the bottom of the equipment support frame 2, and the movable end of the supporting block driving source is fixedly connected to the bottom of the movable supporting block 83.

[0104] The top of the first guiding ring 81 is provided with a supporting block avoidance hole through which the movable supporting block 83 passes. The supporting block avoidance hole penetrates through to the bottom of the equipment support frame 2, and the supporting block driving source is located below the supporting block avoidance hole. During operation, the supporting block driving source drives the movable supporting block 83 to be movably arranged within the supporting block avoidance hole or to be arranged upward within the second guiding channel 85.

[0105] The lifting connection module 67 includes a lifting guide rod 671, a lifting connection plate 672, a lifting support frame 673, and lifting rollers 674. The lifting guide rod 671 is vertically penetrated through the second disc body 4 and the first disc body 3. Specifically, a linear bearing seat is arranged at the bottom of the first disc body 3, and the outer periphery of the lower half section of the lifting guide rod 671 slides along the linear bearing. One side of the lifting connection plate 672 is fixedly connected to the top end of the lifting guide rod 671, and the other side thereof is fixedly connected to the outer side wall of the material cup 6.

[0106] The lifting rollers 674 are rotatably arranged on the front side surface of the lifting support frame 673, and the lifting rollers 674 slide along the first guiding channel 84 or the second guiding channel 85.

[0107] In the initial state, the lifting rollers 674 are located within the first guiding channel 84, so that there is a clearance between the material cup 6 and the container body 1 located within the receiving bayonet 31;

[0108] The block driving source drives the movable supporting block 83 to rise from the supporting block avoidance hole into the second guiding channel 85. When the movable supporting block 83 is located in the second guiding channel 85, the top of it is flush with the top of the first arc-shaped convex part 811.

[0109] When the first disc body 3 rotates, it drives the lifting roller 674 to move along the first guiding channel 84 onto the movable supporting block 83.

[0110] After the container body 1 located in the guiding and rectifying station 53 finishes its work, the block driving source drives the movable supporting block 83 to reset into the supporting block avoidance hole. Under the action of gravity, the lifting guide rod 671 moves downward so that the lifting guide wheel is arranged in the second guiding channel 85. Meanwhile, the material cup 6 moves downward, driving the insertion position 66 to be inserted into the first partition plate 11, and further making the four material passing channels 62 of the material cup 6 respectively vertically aligned with the four material storage cavities 12.

[0111] Subsequently, the first disc body 3 continues to rotate, driving the container body 1 to be successively arranged in the filling station 54, filling materials into the four material storage cavities 12 through the filling device, and arranged in the finishing station 55, where the vibrating device 551 acts on the bottom of the container body 1 to ensure that the materials are filled in place.

[0112] Then, the first disc body 3 continues to rotate, moving the filled container body 1 to the discharging end. Meanwhile, the lifting roller 674 moves from the second guiding channel 85 to the first guiding channel 84. At this time, the lifting guide rod 671 moves upward accordingly, making the arc-shaped insertion piece 65 of the material cup 6 away from the opening of the container body 1.

[0113] The first disc body 3 rotates to drive the filled container body 1 to move from the discharging end to the second conveying device 52, and is conveyed forward by the second conveying device 52 to the next process.

[0114] Compared with the prior art, in this embodiment, the discharging end of the material cup 6 is provided with an insertion connection to be connected with the container body 1, so that the material cup 6 is located inside the container body 1, thereby ensuring accurate filling position and preventing material leakage.

[0115] The above connection method of the material cup 6 and the container body 1, in cooperation with the movement of the lifting roller 674 along the first guiding channel 84 and the second guiding channel 85, restricts its vertical movement stroke. When the container cup vibrates, the material cup 6 will not generate vertical jumping, prolonging its service life.

[0116] The lifting mode of the material cup 6 adopts a mechanical mechanism, which has the advantages of small floor area, few used spare parts, and stable working effect, thereby reducing the equipment manufacturing and use costs.

[0117] Refer to Figure 1 、 Figure 4As shown in the figure, a bottle discharging device 521 is provided outside the input end of the second conveying device 52. The bottle discharging device 521 includes a bottle discharging support frame 521-1, a bottle discharging driving source 521-2, and a swing arm 521-3. In this embodiment, the bottle discharging driving source 521-2 is a single-rod cylinder.

[0118] The bottle discharging support frame 521-1 is fixedly arranged at the top of the equipment support frame 2 along the moving direction of the container body 1, and it is located outside the second conveying device 52. The bottle discharging driving source 521-2 is fixedly arranged on the bottle discharging support frame 521-1. The swing arm 521-3 is movably arranged below the first disc body 3 or above the input end of the second conveying device 52.

[0119] A swing shaft is arranged at the bottom of one end of the swing arm 521-3. One end of the swing shaft is fixedly connected to the bottom of the swing arm 521-3, and the other end of the swing shaft is rotatably arranged on the bottle discharging support frame 521-1. The outer periphery of the other end of the swing shaft is rotatably connected to the bottle discharging support frame 521-1 through a bearing seat. The movable rod of the bottle discharging driving source 521-2 is connected to the end of the other end of the swing shaft through a spherical bearing.

[0120] During operation, when the first disc body 3 drives the filled container body 1 to move onto the second conveying device 52, the can discharging driving source drives the swing arm 521-3 to rotate from below the first disc body 3 towards the output end direction of the second conveying device 52. During the rotation of the swing arm 521-3, the container body 1 is separated from the receiving bayonet 31.

[0121] In this embodiment, the separation efficiency and effect of the container body and the first disc body are improved by setting the bottle discharging device. The bottle discharging device as a whole adopts a mechanical structure, which has the advantages of stable working effect and convenient maintenance.

[0122] Of course, the above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention.
