[0049] The infeed starwheel device is a core component connecting the upstream and downstream in the aluminum can production line, and its performance directly affects production efficiency and product quality. The existing infeed starwheel devices usually use a motor drive and gear transmission to meet the operation of the equipment, and lubricating oil needs to be added during the operation of the gear transmission. However, with the continuous development of society, the market's hygiene requirements for products are becoming increasingly strict. The oil used for gear lubrication will affect the production environment during the operation of the equipment and cannot meet the requirements of ultra-clean filling production. At the same time, with the development of technology, the requirements for high-speed filling and packaging in the aluminum can production line are getting higher and higher, and filling and sealing machines with a production capacity of 1500 cans per minute and above are almost blank. During the operation of gear-driven equipment, as the speed increases, problems such as vibration, gear wear, and noise will become more and more serious, thus affecting the stability of equipment filling. Especially in high-speed production lines with a speed of 60,000 cans per hour and above, these problems will become more prominent. Therefore, the existing infeed starwheel devices also cannot meet the needs of customers for high-speed filling.

[0050] This application proposes a barrel seat type servo-driven infeed starwheel device for an aluminum can filling machine. This device cancels the platen support, gear meshing transmission, and gear lubrication of the original equipment, adopts a barrel seat type structure and a lubrication-free system, and does not require oil lubrication, which can avoid the impact of lubricating oil on the production space environment and meet the requirements of ultra-clean production. At the same time, the equipment runs stably at high speed, has a fast response speed, and low noise, which can greatly improve the competitiveness of the equipment.

[0051] Please refer to Figure 1-16, the present invention is a bucket - seat type servo - driven can - feeding star - wheel device, including a base, a star - wheel structure 9, a servo motor 5, a cross - beam 3, a guide rail 12, an outer - frame structure 14, a guide structure 19, etc. Among them, the base is used as a bottom - support structure, and it is set as a bucket - seat type structure, that is, the base can include a shaft - seat body 1 and a support cylinder 2. Among them, the shaft - seat body 1 can be set as a cylindrical structure, and a cavity is opened inside it. The support cylinder 2 is fixedly connected to the shaft - seat body 1 to connect the upper structure and install the servo motor 5. The way of fixedly connecting the support cylinder 2 and the shaft - seat body 1 can be bolt connection, or other fixed - connection methods. A number of cross - beams 3 are arranged on the side of the base. The cross - beams 3 can be horizontally arranged transversely to support the upper structure subsequently. Specifically, one end of the cross - beam 3 is fixedly connected to the side of the support cylinder 2. A number of the cross - beams 3 can be arranged around the base, and they can be evenly arranged, or arranged according to the support requirements of the upper structure.

[0052] Please refer to Figure 1-16 , in one embodiment of the present invention, a lifting - adjustment component 4 can be arranged at the bottom end of the shaft - seat body 1 to adjust the height of the device according to the usage situation. The lifting - adjustment component 4 can select a hydraulic or pneumatic adjustment mechanism, or a sliding - sleeve rod structure, or a screw - rod adjustment structure. As an example, the lifting - adjustment component 4 can include a screw rod, a locking part, and a chassis. One end of the screw rod is fixedly connected to the chassis, and the other end passes through the shaft - seat body 1 and is in threaded cooperation with the shaft - seat body 1. The locking part is used to lock the positions of the shaft - seat body 1 and the screw rod. By setting the chassis, the stability of the whole base is ensured. The screw rod is arranged along the length direction of the shaft - seat body 1. When needed, the height of the shaft - seat body 1 can be adjusted through threaded cooperation, and after adjustment, it is locked by the locking part.

As an example, the connection component 15 can include a blanking plate, a shrink - fit sleeve, and a connection plate. The size of the connection plate is the same as the size of the shaft hole and is located in the shaft hole. The size of the blanking plate is larger than the size of the shaft hole. The shrink - fit sleeve is made of a flexible material, such as rubber. Bolts pass through the blanking plate and the shrink - fit sleeve and are in cooperation with the threaded holes opened on the connection plate. During the process of tightening the bolts, the blanking plate and the connection plate approach and squeeze the shrink - fit sleeve to cause it to deform and abut against the inner wall of the shaft hole, completing the fixation of the connection component 15 relative to the shaft hole. By setting bolts facing outwards on the blanking plate, it can be used for connection and fixation with other structures.

In the attached Figure 4 it enters from the right side in the figure, and the in-place signal is detected by the sensor. The output end of the conveyor belt is connected to the input end of the guide rail of the star wheel device ( Figure 4Dock with the right side of the middle) and is used to input the tank body into the star wheel device and enter the slot on the star wheel structure during the rotation of the star wheel device; Rotation: The star wheel rotates at a set angle / speed, and the tank body moves along with the rotation of the star wheel structure. During the rotation process, the bottom of the tank body is supported by the guide rail, and the upper part is stabilized by the pressing plate. Its inner and outer sides are respectively limited by the star wheel structure and the outer frame structure, so as to maintain stability during transportation until it is transferred to the output end (in Figure 4 it is the upper left corner in), and the tank body is transported to the filling or can sealing station through the combined action of the guiding structure and the outer frame structure (such as Figure 16 ); Positioning and locking: At the target station, the tank body is fixed (such as a lifting platform or a gripper) to ensure the filling / sealing accuracy. Tank discharging stage: After the process is completed, the star wheel continues to rotate and transfers the tank body to the discharging conveyor belt.

[0065] In this application, the base is set as a barrel seat structure, and a servo motor is arranged inside it to directly drive the rotation of the star wheel structure, thereby driving the tank body in the slot for transportation. The platen support, gear meshing transmission, and gear lubrication of the original equipment are cancelled. Oil lubrication is not required, which can avoid the impact of lubricating oil on the production space environment and meet the requirements of ultra-clean production. Moreover, the overall structure of this device is stable, and there are no problems such as easy vibration and large noise in the existing equipment at high speeds. The device runs stably at high speeds, has a fast response speed, and low noise, which can greatly improve the competitiveness of the equipment.
