Description

Technical Field

[0001] The present invention relates to the technical field of equipment circulation, and in particular to a circulation device suitable for aluminum can equipment. Background Art

[0002] A production line refers to the route taken by a product during the manufacturing process, starting from the entry of raw materials into the production site and continuing through a series of processes such as processing, transportation, assembly, and inspection. Depending on the type and structure of the product, the flow of materials between stations in the production line often requires the use of specialized flow equipment.

[0003] Aluminum can production involves many processes, and each process technology requires different mechanical equipment to complete. In order to achieve automated connection between various equipment, the flow between process equipment is an important connection process in automated production equipment to achieve fully automated production.

[0004] The transfer device is an important connecting component in the automated production process. The existing device inserts the can into the chain guide rod of another device through an inclined conveyor table, and then transports it to another device to complete the process in the other device. Its working method is as follows:

[0005] like Figure 1 As shown, the existing inclined conveyor mechanism is to place the product on the previous equipment on the guide rod of the synchronous chain using synchronous technology. The product on the conveyor is placed on the guide rod of the synchronous chain, and then enters the process action of another mechanical equipment. The existing technology all uses the inclined flow technology of the conveyor guide rod. The guide rod inclined flow technology has low efficiency, high failure rate, low product quality, frequent maintenance, rapid spare parts loss, and cannot be produced at high speed. High speed causes the chain and chain rod to jump, and the shaking cannot correctly place the product on the chain rod. When the existing device is applied to the aluminum can production line, the stability rate is low and it is only suitable for low-speed production and low cost. At low speed, the qualified rate is about 85%. If it is at high speed, the qualified rate is about 65%. The efficiency and qualified rate are both low, resulting in increased costs. In addition, the chain often falls off and gets stuck, which increases maintenance costs and seriously affects production efficiency and production quality.

[0006] The production process for single-sided aluminum aerosol cans requires numerous steps to complete a single product. The automated material handling and feeding between these devices is extremely demanding. Improper handling can result in significant product damage and other defects, severely impacting production yield and efficiency. Therefore, to address the flow of semi-finished products between these devices and address the unique structure of aluminum can equipment, it was necessary to design a transfer device suitable for the upstream and downstream processes on the aluminum can production line. Summary of the Invention

[0013] Furthermore, the driving motor is connected to the inner sleeve through a planetary reduction box, and synchronous wheels are provided on the main shaft and the planetary reduction box. The synchronous wheels are connected to a synchronous belt transmission, and the synchronous belt is connected to the inner sleeve transmission.

[0014] Furthermore, it also includes a vacuum distributor, a vacuum pipe joint, and a rotating fixed disc seat. The vacuum distributor distributes the gas into several paths and connects the vacuum pipe joint to make the gas evenly distributed on the rotating fixed disc seat. The gas is evenly distributed on the guide rod through the sprocket. The friction suction cup is provided with an air hole, and the air hole is connected to the suction strip assembly.

[0015] Furthermore, it also includes an adjustment component, which includes an adjustment synchronous wheel, an adjustment manual wheel, an adjustment small gear and an adjustment large gear.

[0037] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] like Figure 1-10 As shown, a flow device suitable for aluminum can equipment is installed in an auxiliary area of the aluminum can production equipment and operates along with the aluminum can production line. When no aluminum cans arrive, the flow device operates with low energy consumption and is in a standby state. The flow device includes a main shaft 1, a suction bar assembly, a cam barrel 33, a friction suction cup 14, and a drive motor 20. The suction bar assembly is arranged around the cam barrel 33, which is fixed to the main shaft 1. The suction bar assembly is connected to the friction suction cup 14. The drive motor 20 drives the main shaft 1 to rotate, causing the suction bar assembly on the cam barrel 33 to rotate, sucking or releasing aluminum cans at a preset position. Preferably, the flow device is provided with a lifting jack 47, which can adjust the height of the flow device.

[0039] like Figure 4-7As shown, the suction strip assembly includes a sliding seat 48, a vacuum suction strip 43, a chain rod positioning block 44, and a bearing seat 45. The bearing seat 45 is located at the lower end of the sliding seat 48, the vacuum suction strip 43 is located at the upper end of the sliding seat 48, and the chain rod positioning block 44 is located at the rear end of the vacuum suction strip 43. The suction strip assembly is mounted on the cam cylinder 33 through the cooperation of the bearing seat 45 and the sliding guide rod 51. The vacuum suction strip 43 is made of PE food-grade polymer material, which does not cause any harmful effects on the aluminum can when in contact with it, ensuring the safety of the aluminum can. The nozzle on the vacuum suction strip 43 is made of polyurethane and will not damage the inner wall and outer surface of the aluminum can. When the aluminum can is transported to the bottom of the circulation device by means of a conveyor table, the vacuum suction strip 43 is aligned with the aluminum can, and the nozzle is aligned with the aluminum can and sucked. The introduction sprocket 42 is used to guide the chain into the circulation device, and is transported forward to the bottom of the sprocket 15 on the chain through the cam cylinder 33. The aluminum can is then transported to the workstation of the next process by the chain to complete the circulation of the production equipment.

[0040] like Figure 8 and 9 As shown, the cam barrel 33 is fixedly mounted with a front support plate 34 and a rear support plate 31 at each end. Both the front support plate 34 and the rear support plate 31 have through-holes, and a clamping mount 35 is positioned in the through-holes of the rear support plate 31. The cam barrel 33 is secured to the spindle 1 via these through-holes. Made of MC nylon, the cam barrel 33 exhibits excellent self-lubrication, ensuring smooth operation with the bearing seat 45 of the vacuum strip 43. This ensures stable operation of the flow mechanism over extended periods of operation and enables precise positioning to better meet practical needs.

[0041] like Figure 8 and 9As shown, the first bearing 4, the third bearing 28 and the fifth bearing 38 are all arranged on the main shaft 1. The rear part of the main shaft 1 is provided with an inner sleeve 6 for driving the sliding groove 36. The inner sleeve 6 is provided with an outer sleeve 7. The outer sleeve 7 has a V-shaped guide groove. The outer sleeve 7 is slidably arranged on the sliding block 12. The outer sleeve 7 can be slidably adjusted, and the second bearing 5 is arranged on the outer sleeve 7. The main shaft 1 is also provided with a support plate 39 and a sensor plate 50. The inner sleeve 6 is provided with a drive pulley 3 and a sprocket 15. A support 16 is fixedly mounted on the sprocket 15. A chain rod positioning plate 17 is fixedly mounted on the support 16. The chain rod positioning plate 17 has a V-shaped notch for positioning the chain rod so that it is accurately aligned with the aluminum can. The support plate 39 is connected to the sliding groove 36. A guide rod 40 is provided on the sprocket 15 and the support plate 39. A guide rod limit cap 41 is provided at the front end of the guide rod 40. A vacuum strip 43 is provided on the guide rod 40. The fourth bearing 30 on the guide groove rotates with the sliding groove 36, driving the vacuum strip 43 to rotate with the cam cylinder 33. The vacuum strip 43 is stuck in the groove of the cam cylinder 33. The sliding groove 36 drives the vacuum strip 43 to perform linear and rotational motion on the guide rod 40. The cam cylinder 33 causes the vacuum strip 43 to move back and forth, and the sliding groove 36 causes the vacuum strip 43 to rotate.

[0042] like Figure 10 and 11 As shown, the drive motor 20 is mounted on a frame 24, which is fixedly connected to the wall panel 11 via a fixed frame 8. The drive motor 20 is connected to the inner sleeve 6 via a planetary reduction gear 21. Synchronous pulleys 22 are provided on both the main shaft 1 and the planetary reduction gear 21. Synchronous pulleys 22 are in driving connection with a synchronous belt 23, which is in driving connection with the inner sleeve 6. When the sensor board 50 senses an aluminum can, it transmits the information to the PLC program controller, which sends a command to the servo controller to start the drive motor 20. Due to the high speed of the drive motor 20, the planetary reduction gear 21 reduces the speed to an appropriate range. An overload clutch 2 is connected to the main shaft 1. If a can falls or gets stuck during transportation, the overload clutch 2 provides overload protection, preventing a large number of cans from falling or being damaged.

[0043] like Figure 2 and 12As shown, the apparatus also includes an adjustment assembly, which includes an adjustment synchronous wheel 25, an adjustment manual wheel 52, an adjustment pinion 27, and an adjustment gear 29. The adjustment synchronous wheel 25 and the adjustment manual wheel 52 are respectively connected to the adjustment pinion 27, the adjustment seat 26 is connected to the adjustment manual wheel 52, the adjustment pinion 27 is connected to the adjustment gear 29, and the adjustment gear 29 is connected to the friction suction cup 14. Rotation of the adjustment synchronous wheel 25 adjusts the speed at which the suction bar assembly absorbs or releases aluminum cans, and rotation of the adjustment manual wheel 52 adjusts the position of the air hole. The fixed support rod 19 is used to secure the stop bar 32 and the limit plate 37, both of which are used to prevent aluminum cans from falling into the vacuum suction bar 43.

[0044] like Figure 3 、 10 As shown in Figure 11, the system also includes a vacuum distributor 49, a vacuum pipe joint 9, and a rotating fixed disc 13. The vacuum distributor 49 distributes the air into several paths and connects to the vacuum pipe joint 9. The vacuum pipe joint 9 passes through the joint fixing plate 10, evenly distributing the air to the rotating fixed disc 13. The air is then evenly distributed to the guide rod 40 via the sprocket 15. The friction suction cup 14 is provided with air holes, which are connected to the suction bar assembly. Each vacuum suction bar 43 has the same suction force, preventing uneven distribution, such as some vacuum suction bars 43 having weak suction and causing cans to fall. The protective plate 18 is mounted on the wall panel 11, and the friction suction cup 14 is mounted within the protective plate 18. As the friction suction cup 14 rotates, the suction and degassing positions change. The friction suction cup 14 determines the starting suction and degassing positions, and the vacuum suction bar 43 begins to operate, sucking the aluminum cans and completing the transportation process. The friction suction cup 14 has half holes and the other half no holes. The main purpose is to control the flow equipment to start sucking the aluminum can when the aluminum can reaches the first preset point A, and when the aluminum can reaches the second preset point B, the suction is closed.

[0045] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications made within the spirit of the main technical solution of the present invention are intended to be included within the scope of protection of the present invention.
