Description

Technical Field

[0001] The invention relates to the technical field of filling equipment, and in particular to a filling equipment for a multi-cavity container. Background Art

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

[0003] With the diversification of market demands (such as the demand for diversified, personalized and multifunctional products in the pharmaceutical, cosmetic and food industries), multi-cavity containers have emerged. The multi-cavity design integrates multiple independent cavities to simultaneously fill different materials or different doses of the same material, significantly improving production efficiency and product consistency.

[0004] However, the existing rotary filling equipment can only fill single-cavity packaging cavities when in use. When sealing multi-cavity products, it is necessary to add filling stations. It is not possible to fill multiple cavities at the same time, which greatly reduces production efficiency.

[0005] Since the packaging container rotates during transportation and delivery, there are position deviations between the multiple storage cavities in the packaging container and the material cup's material passageway. To ensure the filling effect, the geometric symmetry of the multi-cavity container and the material cup is extremely high. Therefore, during filling, the position and angle of the upper and lower alignment of the material cup and the cavity must be accurately controlled. Manual alignment is inefficient, inaccurate, and prone to errors.

[0006] In this regard, the prior art uses a matrix-based multi-nozzle structure and a step-by-step positioning system to position the containers for synchronous filling of multi-cavity containers, and cooperates with a visual inspection device to perform position calibration. However, the above method has the problems of complex structure, high cost and low production efficiency.

[0007] At the same time, the material cup in the existing turntable filling device is directly fixedly connected to the turntable, and the packaging container generally needs to make vertical movements during the filling process to ensure that the filling is in place. At this time, the packaging container will intermittently hit the material cup, causing the material cup to swing up and down, resulting in the deviation of the material passage and the cavity, affecting the filling effect and reducing the service life of the material cup. Summary of the invention

[0086] The movable support block 83 is driven by a support block driving source and is arranged at the starting end of the second guide channel 85 so as to be able to rise and fall. In this embodiment, the support block driving source is a cylinder. Specifically, the movable support block 83 is opposite to the guide positioning device 7 in front and back.

[0087] The support block driving source is fixedly arranged at the bottom of the equipment support frame 2 , and the movable end of the support block driving source is fixedly connected to the bottom of the movable support block 83 .

[0088] The top of the first guide ring 81 is provided with a support block avoidance hole for the movable support block 83 to pass through, the support block avoidance hole penetrates to the bottom of the equipment support frame 2, and the support block driving source is located below the support block avoidance hole. When working, the support block driving source drives the movable support block 83 to be movable and set in the support block avoidance hole or to be set upward in the second guide channel 85.

[0089] The lifting connection module 67 includes a lifting guide rod 671, a lifting connection plate 672, a lifting support frame 673 and a lifting roller 674. The lifting guide rod 671 is vertically arranged on the second plate body 4 and the first plate body 3. Specifically, a linear bearing seat is arranged at the bottom of the first plate body 3, and the outer periphery of the lower half 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 of the lifting guide rod 671, and the other side thereof is fixedly connected to the outer wall of the material cup 6.

[0090] The lifting roller 674 is rotatably disposed on the front side of the lifting support frame 673 , and the lifting roller 674 slides along the first guide channel 84 or the second guide channel 85 .

[0091] In the initial state, the lifting roller 674 is located in the first guide channel 84, so that the material cup 6 and the container body 1 located in the receiving bayonet 31 are spaced apart; The support block driving source drives the movable support block 83 to rise from the support block avoidance hole to the second guide channel 85. When the movable support block 83 is located in the second guide channel 85, the top of the movable support block 83 is flush with the top of the first arc-shaped protrusion 811. When the first plate 3 rotates, it drives the lifting roller 674 to move along the first guide channel 84 to the movable support block 83; When the container body 1 in the guiding station 53 completes the work, the support block driving source drives the movable support block 83 to return to the support block avoidance hole. Under the action of gravity, the lifting guide rod 671 moves downward so that the lifting guide wheel is set in the second guide channel 85. At the same time, the material cup 6 moves downward to drive the insertion position 66 to be inserted in the first partition 11, so that the four material passage channels 62 of the material cup 6 are respectively aligned with the four material storage chambers 12 up and down. Subsequently, the first plate 3 continues to rotate to drive the container body 1 to be sequentially arranged in the filling station 54 to fill materials into the four material storage cavities 12 through the filling device, and is arranged in the sorting station 55 to act on the bottom of the container body 1 through the vibration device 551 to ensure that the materials are filled in place; Next, the first plate 3 continues to rotate to move the filled container body 1 to the discharge end. At the same time, the lifting roller 674 moves from the second guide channel 85 to the first guide channel 84. At this time, the lifting guide rod 671 moves upward, so that the arc-shaped insert 65 of the material cup 6 is away from the opening of the container body 1. The first plate 3 rotates to drive the filled container body 1 to move from the discharge end to the second conveying device 52 , and is then transported forward to the next process by the second conveying device 52 .
