Description

Technical Field

[0001] The present invention relates to the technical field of equipment transfer, and particularly relates to a transfer device applicable to aluminum can equipment. Background Art

[0002] A production line refers to the route through which a product is produced, that is, starting from the raw materials entering the production site, passing through a series of technological processes such as processing, transportation, assembly, and inspection. According to the different types and structures of products, the transfer between each workstation in the production line often requires the assistance of specialized transfer equipment for material transfer.

[0003] The production of aluminum cans involves many processes, and each process technology requires different mechanical equipment to complete. In order to achieve automatic connection between various equipment, the transfer between process equipment is an important connection process in automatic production equipment to achieve fully automatic production.

[0004] The transfer device is an important connecting component in the automatic production process. The existing device inserts the cans onto the chain guide rod of another device through an inclined conveyor table and then transports them to another device. After the process is completed on another device, its working method is as follows: Such as Figure 1 As shown, the existing inclined conveyor table mechanism is to use the synchronous technology of the inclined flow conveyor table and the conveyor chain to place the products on the upper device onto the guide rod of the synchronous chain, so as to enter the process operation of another mechanical equipment. The existing technologies all adopt the inclined flow technology of the conveyor table guide rod. The inclined flow technology of the guide rod has low efficiency, high failure rate, low product quality, frequent maintenance, fast spare part loss, and cannot produce at high speed. High speed causes the chain and the link rod to jump and vibrate, and the products cannot be correctly placed on the link rod. When the existing device is applied to the aluminum can production line, the stability rate is low, and it is only applicable to the situation of low-speed production and low construction cost. In the case of low speed, the qualified rate is about 85%. If it is in the case of high speed, the qualified rate is about 65%. Both the efficiency and the qualified rate are relatively low, resulting in an increase in cost; and the chain often falls off, causing jams, which increases the maintenance cost and seriously affects the production efficiency and production quality.

[0005] In the production process of single-sided aluminum aerosol can products, many processes are required to complete the normal production of a product. The automatic feeding and feeding between such equipment are extremely strict for the product. If the transportation is not good, a large number of product damages and other defects will occur, seriously affecting the qualified rate and efficiency of production. Therefore, in order to solve the transfer of semi-finished products between such equipment and at the same time for the special structure between aluminum can equipment, it is necessary to design a transfer device applicable to the upper and lower process equipment on the aluminum can production line. Summary of the Invention

The fourth bearing on the guide groove rotates along with the sliding groove, driving the vacuum suction strip to rotate along with the cam cylinder.

[0012] Further, the driving motor is connected to the inner sleeve through a planetary reduction gearbox. Synchronous pulleys are arranged on both the main shaft and the planetary reduction gearbox. The synchronous pulleys are in transmission connection through a synchronous belt. The synchronous belt is in transmission connection with the inner sleeve.

[0013] Further, a vacuum distributor, a vacuum tube joint and a rotary fixed disc seat are also included. The vacuum distributor distributes the gas volume into several paths and connects the vacuum tube joint, so that the gas volume is evenly distributed on the rotary fixed disc seat. The gas volume is evenly distributed on the guide rods through the sprocket. Air holes are arranged on the friction suction cup. The air holes are connected to the suction strip assembly.

[0014] Furthermore, it also includes an adjustment component, which includes an adjustment synchronous wheel, an adjustment manual wheel, an adjustment pinion and an adjustment gear.

Detailed implementation manners

[0017] To make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] As Figures 1-10 shown, a transfer device applicable to aluminum can equipment is provided in an auxiliary area of the aluminum can production device and operates along with the aluminum can production line. When no aluminum can arrives, the transfer device operates with low energy consumption and is in a standby state. It includes a main shaft 1, a suction strip assembly, a cam barrel 33, a friction suction cup 14, and a drive motor 20. The suction strip assembly is arranged on the circumferential side of the cam barrel 33. The cam barrel 33 is fixedly arranged on the main shaft 1. The suction strip assembly is connected to the friction suction cup 14. The drive motor 20 drives the main shaft 1 to rotate, causing the suction strip assembly on the cam barrel 33 to rotate, and sucking or releasing aluminum cans at a preset position. Preferably, a lifting jack 47 is provided on the transfer device, and the lifting jack 47 can adjust the height of the transfer device.

[0019] As Figures 4-7 shown, the suction strip assembly includes a sliding seat 48, a vacuum suction strip 43, a link positioning block 44, and a bearing seat 45. The bearing seat 45 is arranged on the lower end surface of the sliding seat 48. The vacuum suction strip 43 is arranged on the upper end surface of the sliding seat 48. The link positioning block 44 is arranged at the tail of the vacuum suction strip 43. The suction strip assembly is arranged on the cam barrel 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 and will not cause any harmful effects on the aluminum can when contacting 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 lower part of the transfer device by means of a conveyor table, after the vacuum suction strip 43 is aligned with the aluminum can, the nozzle is aligned with the aluminum can and sucks it. The guiding sprocket 42 is used to guide the chain into the transfer device, and it is transported forward through the cam barrel 33 to the bottom of the sprocket 15 on the chain, and then the aluminum can is transported to the work station of the next process through the chain, completing the transfer of the production equipment.

[0020] As Figure 8 and 9 shown, front support fixing plates 34 and rear support fixing plates 31 are respectively fixedly arranged at both ends of the cam barrel 33. The front support fixing plates 34 and the rear support fixing plates 31 have through holes. A clamping fixing seat 35 is arranged on the through holes of the rear support fixing plate 31. The cam barrel 33 is fixedly arranged on the main shaft 1 through the through holes. The cam barrel 33 is made of MC nylon material and has excellent self-lubricating function, ensuring smooth operation between it and the bearing seat 45 of the vacuum suction strip 43. Long-term operation can ensure the stable operation of the transfer device, can accurately position, and better meet the actual requirements.

[0021] As 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. A inner sleeve 6 for driving the sliding groove 36 is arranged at the rear of the main shaft 1. An outer sleeve 7 is arranged on the inner sleeve 6. 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. The second bearing 5 is arranged on the outer sleeve 7. A support plate 39 and a sensor plate 50 are also arranged on the main shaft 1. A transmission pulley 3 and a sprocket 15 are arranged on the inner sleeve 6. A support column 16 is fixedly arranged on the sprocket 15. A link positioning plate 17 is fixedly arranged on the support column 16. The link positioning plate 17 has a V-shaped notch, and the notch is used to position the link so that the link can accurately align with the aluminum can. The support plate 39 is connected to the sliding groove 36. Guide rods 40 are arranged on the sprocket 15 and the support plate 39. A guide rod limit cover 41 is arranged at the front end of the guide rod 40. A vacuum suction strip 43 is arranged on the guide rod 40. The fourth bearing 30 on the guide groove rotates with the sliding groove 36, driving the vacuum suction strip 43 to rotate with the cam cylinder 33. The vacuum suction strip 43 is stuck on the groove of the cam cylinder 33. The sliding groove 36 drives the vacuum suction strip 43 to perform linear motion and rotational motion on the guide rod 40. The cam cylinder 33 makes the vacuum suction strip 43 move back and forth, and the sliding groove 36 makes the vacuum suction strip 43 perform rotational motion.

[0022] As Figure 10 and 11 shown, the drive motor 20 is arranged on the frame 24. The frame 24 is fixedly connected to the wall panel 11 through the fixing frame 8. The drive motor 20 is connected to the inner sleeve 6 through the planetary reduction gearbox 21. Synchronous pulleys 22 are arranged on both the main shaft 1 and the planetary reduction gearbox 21. The synchronous pulleys 22 are in transmission connection with the synchronous belt 23. The synchronous belt 23 is in transmission connection with the inner sleeve 6. When the sensor plate 50 senses the aluminum can, the sensor plate 50 transmits the information to the PLC program controller. The PLC program controller sends an instruction to the servo controller to start the drive motor 20. Since the rotational speed of the drive motor 20 is relatively high, the speed is reduced to a suitable range through the planetary reduction gearbox 21. The overload clutch 2 is connected to the main shaft 1. During the transportation process, when there is a situation of can dropping or can jamming, the overload clutch 2 provides overload protection and will not cause a large number of cans to drop and be damaged.

[0023] As Figure 2 and 12As shown, it further includes an adjustment assembly. The adjustment assembly includes an adjustment synchronous pulley 25, an adjustment manual wheel 52, an adjustment pinion 27, and an adjustment gear 29. The adjustment synchronous pulley 25 and the adjustment manual wheel 52 are respectively in transmission connection with the adjustment pinion 27. The adjustment seat 26 is in transmission connection with the adjustment manual wheel 52. The adjustment pinion 27 is in transmission connection with the adjustment gear 29. The adjustment gear 29 is in transmission connection with the friction suction cup 14. When the adjustment synchronous pulley 25 rotates, the speed at which the adjustment suction bar assembly sucks or releases aluminum cans is adjusted. When the adjustment manual wheel 52 rotates, the position of the air holes is adjusted. The fixed support rod 19 is used to fix the retaining bar 32 and the limiting plate 37. Both the retaining bar 32 and the limiting plate 37 are used to prevent aluminum cans from falling into the vacuum suction bar 43.

[0024] As Figure 3 , 10 and 11 show, it further includes a vacuum distributor 49, a vacuum tube joint 9, and a rotating fixed disk seat 13. The vacuum distributor 49 distributes the gas volume into several paths and connects to the vacuum tube joint 9. The vacuum tube joint 9 passes through the joint fixing plate 10 to evenly distribute the gas volume on the rotating fixed disk seat 13. The gas volume is evenly distributed on the guide rod 40 through the sprocket 15. There are air holes provided on the friction suction cup 14, and the air holes are connected to the suction bar assembly. Each of the vacuum suction bars 43 has the same suction force, so there will be no uneven distribution, and the situation where some of the vacuum suction bars 43 have small suction force and the cans fall off will not occur. The protective plate 18 is arranged on the wall plate 11, and the friction suction cup 14 is arranged inside the protective plate 18. When the friction suction cup 14 rotates, the positions of air intake and air release change. The friction suction cup 14 determines the starting air intake position and the air release position. The vacuum suction bar 43 starts to work, sucks the aluminum cans, and completes the transportation work. Half of the friction suction cup 14 has holes and half has no holes. The main purpose is to control the transfer device to start sucking the aluminum cans when the aluminum cans reach the first preset point A, and when the aluminum cans reach the second preset point B, the air intake is closed.

[0025] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. All modifications made according to the spirit essence of the main technical solution of the present invention should be covered within the protection scope of the present invention.
