Technical Field

[0001] The invention relates to a self-rotating conveying device. Background Art

[0002] In the field of aseptic filling, any equipment in a sterile environment is required to reduce as much as possible the structures that are prone to hygiene problems, such as too many joints, corners, deep seams, overly exposed gaps, etc., through such a design, the surface area of ​​the equipment can be effectively reduced and the surface finish and smoothness can be improved. Therefore, too many distribution connection pipelines or connection structures on the surface of the equipment are not conducive to the applicability of the equipment in the field of aseptic filling.

[0003] In the prior art, the membrane cap conveying device used in the field of aseptic filling is not conducive to maintaining a sterile state or a high clean state for a long time in an aseptic environment due to its complex surface structure, especially the excessive arrangement of pipelines. This type of membrane cap conveying device is a self-rotating conveying device, which is provided with a self-rotating cylindrical barrel, and the surface of the barrel is provided with suction cups arranged straightly and equidistantly along the generatrix, and rows of straight suction cups are distributed at equal angles on the barrel. The suction cups work under the negative pressure conditions provided by the air pipes, which are arranged outside the barrel and exposed to the entire surface of the equipment. There are many suction cups, and therefore, there are a large number of air pipes. The air pipes are connected to the external air circuit in a series-parallel connection mode, and the branch structure formed carries many connection gaps. These structures are not conducive to establishing a stable aseptic state. Therefore, the existing self-rotating conveying device has design defects in the use requirements of aseptic filling.

[0014] The adsorption component includes a suction cup 5, a distribution pipe 6, a support pipe 7, and a lifting rod 8, wherein the distribution pipe 6, the support pipe 7, and the lifting rod 8 are all straight structures. Two support pipes 7 are fixedly installed on the distribution pipe 6, and the two support pipes 7 are in a parallel position relationship. Each support pipe 7 is in a vertical connection relationship with the distribution pipe 6. The suction cup 5 is installed on the distribution pipe 6 and is arranged straightly at equal intervals. The support pipe 7 is slidably connected to the cylinder 1 through a sliding sleeve, and a corrugated pipe is also provided on the outside of the sliding sleeve, so that the support pipe 7 can make a linear reciprocating motion in the radial direction of the cylinder 1, and the distribution pipe 6 is parallel to the center line of the cylinder 1. One end of the support pipe 7 is connected to the distribution pipe 6 and is located outside the cylinder 1, and the other end of the support pipe 7 is located inside the cylinder 1. The lifting rod 8 is fixed to the outside of the support pipe 7 and is located inside the cylinder 1. Bearings are installed at both ends of the lifting rod 8.

[0015] The gas path component includes a rotating shaft 9 and an air separator ring 11. The rotating shaft 9 is a T-shaped structure as a whole, which is composed of a cylindrical part and a disc-shaped part.

The disc-shaped part of the rotating shaft 9 is fixedly connected to the other end of the cylinder 1. After installation, the center line of the rotating shaft 9 coincides with the center line of the cylinder 1. When the cylinder 1 rotates, the rotating shaft 9 and the cylinder 1 move synchronously and in the same direction. An air outlet 10 is provided in the cylindrical part of the rotating shaft 9. Each air outlet 10 is distributed along the center line of the rotating shaft 9 and each air outlet 10 is independent of each other. One end of the air outlet 10 is the air outlet end of the entire gas path component. The air separator ring 11 is a ring-shaped structure component, and an air inlet 12 is provided inside its body. Since the air inlet 12 is distributed along the body of the air separator ring 11, the air inlet 12 is also annular in structure as a whole, but the air inlet 12 is provided with an opening on the surface of the air separator ring 11 for air intake and air outlet. One of the openings of the air inlet 12 is the air inlet end of the entire air path component.

The fixed block and all the air splitter rings 11 are fixedly connected to the end cover Ⅱ3 through a connecting rod. The air splitter ring 11 is movably installed on the rotating shaft 9. The movable mode means that the air splitter ring 11 can rotate around the center line of the rotating shaft 9 but cannot make a linear translational motion along the center line of the movable shaft, that is, the air splitter ring 11 is stationary relative to the rotating shaft 9 in a direction parallel to the center line of the rotating shaft 9.

The air distribution ring 11 is located outside the cylinder 1, so the air inlet end is located outside the rotating cylinder component, and the air inlet end is connected to the external negative pressure pipeline when in use; one end of the rotating shaft 9 faces the inside of the cylinder 1, so the air outlet end is located inside the rotating cylinder component. The adsorption component and the gas path component are connected through a flexible air delivery pipe, one end of the air delivery pipe is connected to the air outlet end on the air outlet 10 of the rotating shaft 9, and the other end of the air delivery pipe is connected to the end of the support pipe 7 located inside the cylinder 1.

The two lifting drive components are arranged separately in the direction around the center line of the cylinder 1, that is, there is an angle greater than zero between the two in the direction around the center line of the cylinder 1. In the actual structure, the angle is greater than 30 degrees, and the size of the angle is generally determined according to the actual working conditions. The size of the angle is the result of adaptive selection. The clamping block 14 is fixed on the piston rod of the electric cylinder 13, and a clamping groove 15 is provided on the clamping block 14. The width of the clamping groove 15 is slightly larger than the outer diameter of the bearing at the end of the lifting rod 8; in the initial state, the piston rod of the electric cylinder 13 is extended, so that the clamping groove 15 is just located within the motion range of the bearing at the end of the lifting rod 8. The working rhythm of the entire self-rotating conveying device is step-by-step, that is, the cylinder 1 rotates a fixed angle and then pauses, then starts and rotates a fixed angle and pauses again, and repeats this process. Every time the cylinder 1 stops moving and does not move, there are exactly two lifting rods 8 located in the slots 15, and after the piston rod of the electric cylinder 13 contracts, the lifting rods 8 are pulled toward the inside of the cylinder 1; after the corresponding action is performed, the piston rod of the electric cylinder 13 extends, the lifting rods 8 return to the initial state, and then the cylinder 1 rotates; during this period, with the cooperation of the negative pressure pipeline, the suction force can be established on the suction cup 5 to transport the conveyed items, most of which are capping films, bottle caps, and cardboard.
