Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0031] Please refer to Figures 1-5 As shown in the figure, the present application is a kind of full-automatic aluminum can production line automatic feeding equipment, including feeding conveying table 1 and screening conveying table 2 which are sequentially arranged along the conveying direction of can cover, screening conveying table 2 is provided with turnover assembly 3, turnover assembly 3 includes turnover plate 31, screening conveying table 2 is fixedly provided with mounting frame 22, mounting frame 22 is fixedly provided with industrial camera 23 at the upper end, industrial camera 23 is located directly above turnover plate 31, the side of turnover plate 31 close to feeding conveying table 1 is provided with material blocking plate 24, material blocking plate 24 is rotatably connected with screening conveying table 2 through torsion spring shaft 243 at both ends, both ends of turnover plate 31 are rotatably connected with screening conveying table 2 through rotating shaft 32 and hollow shaft 33 respectively, one end of hollow shaft 33 is rotatably and sealingly connected with air extraction pipe 34, air extraction pipe 34 drives material blocking plate 24 to rotate to block the can cover when air extraction, screening conveying table 2 is fixedly provided with turnover motor 35 on the side wall, the output end of turnover motor 35 is connected with driving tooth 351, rotating shaft 32 is fixedly provided with transmission tooth 321, driving tooth 351 is engaged with transmission tooth 321.

[0032] Specifically, by setting the turnover assembly 3, the punched can cover falls on the feeding conveying table 1, and is conveyed forward to the screening conveying table 2 through the feeding conveying table 1, when the can cover passes through the turnover plate 31, the industrial camera 23 is used for visual inspection of the can cover to judge whether it is face up, when the can cover is face up, the turnover assembly 3 does not work, at this time the can cover on the turnover plate 31 will continue to be conveyed forward under the conveying push of the rear can cover, when the can cover is back up, the suction pipe 34 starts to suck according to the detection signal, the negative pressure suction force is generated at the upper end of the turnover plate 31 to suck the can cover, the blocking plate 24 is driven to rotate to block the rear can cover during the suction process, at the same time the turnover motor 35 drives the transmission tooth 321 to rotate through the driving tooth 351, the transmission tooth 321 drives the turnover plate 31 to overturn 180° through the rotating shaft 32, so that the can cover is face up and falls on the receiving conveying table 4 to continue to be conveyed forward, so that the automatic detection and turnover process of the can cover can be realized during the conveying and feeding process of the can cover, all the can covers can be conveyed and fed in the correct direction, which is beneficial to the subsequent can cover packaging process of the aluminum can.

[0033] As shown in Figure 6 and Figure 7 , the receiving conveying table 4 is arranged below the screening conveying table 2, which is used for receiving and conveying the can cover overturned by the turnover assembly 3, one end of the screening conveying table 2 and the receiving conveying table 4 is simultaneously connected with the discharging track 5, and the bottom of the discharging track 5 is provided with the discharging conveying table 6.

[0034] Specifically, the originally face-up can cover is conveyed into the discharging track 5 through the screening conveying table 2, and the originally face-up can cover after being overturned is conveyed into the discharging track 5 through the receiving conveying table 4, and the discharging track 5 is used for limiting and guiding the can cover, so that all the can covers can be conveyed in the discharging track 5 in the correct direction all the time, and are converted from the horizontal state to the vertical state, the upright can cover is gradually stacked and automatically aligned along the discharging conveying table 6, so that the integrated conveying process of the can cover feeding, detection, turnover, discharging and discharging is realized.

[0035] As shown in Figure 3 and Figure 4 , the turnover plate 31 is internally provided with the air cavity 311, the upper end of the turnover plate 31 is uniformly provided with the negative pressure air nozzle 312, the negative pressure air nozzle 312 is in communication with the air cavity 311, and the bottom end of the air cavity 311 is in communication with one end of the hollow shaft 33 through the air pipe 313.

[0036] Specifically, when the upside-down can lid is conveyed onto the turnover plate 31, the industrial camera 23 directly above the turnover plate 31 can detect the orientation of the can lid at this time and send a detection signal to the background control unit, and the external air pump starts to draw air through the air suction pipe 34. Since the air suction pipe 34 is connected to the air cavity 311 through the hollow shaft 33 and the air pipe 313, the negative pressure air nozzle 312 at the upper end of the turnover plate 31 continuously draws air and generates negative pressure suction, so that the upside-down can lid can be firmly adsorbed and turned over 180° to make the front face upward. At this time, the control of the air suction pipe 34 stops drawing air, and the turned-over can lid will directly fall on the receiving conveying table 4 under the action of its own gravity.

[0037] It should be noted that, in order to ensure the normal conveying process of the can lid on the turnover plate 31, the top end height of the negative pressure air nozzle 312 should not be higher than the upper surface of the turnover plate 31, so as to prevent the can lid from being blocked.

[0038] As shown in Figures 3-5 , the sieve conveying table 2 is provided with a fixed seat 341 on the side wall, and the air suction pipe 34 is fixedly installed in the fixed seat 341. One end of the air suction pipe 34 is fixedly provided with a rotary joint 342, the hollow shaft 33 is in rotational sealing cooperation with the rotary joint 342, the upper end of the air suction pipe 34 is provided with an outer shell 343, the inner part of the outer shell 343 is provided with a fan blade 345, the fan blade 345 is in rotational cooperation with the outer shell 343 through a pivot shaft 344, and the two ends of the pivot shaft 344 and the torsional spring shaft 243 are connected through the transmission belt 244.

[0039] Specifically, the function of the rotary joint 342 is to keep the hollow shaft 33 in normal rotation while keeping the air suction pipe 34 in communication at all times to ensure normal air suction. During the air suction process, the continuous airflow in the air suction pipe 34 will drive the fan blade 345 to rotate, the fan blade 345 will drive the pivot shaft 344 to rotate synchronously, and the pivot shaft 344 will drive the torsional spring shaft 243 to rotate through the transmission belt 244, so that the blocking plate 24 can be rotated to block the rear can lid and avoid affecting the turnover process.

[0040] As shown in Figure 3 , the sieve conveying table 2 is provided with a clamping seat 241 on both sides, the clamping seat 241 is in clamping cooperation with the blocking plate 24 and blocks it, and the sieve conveying table 2 is provided with a gap slot 242 on both sides for the blocking plate 24 to rotate.

[0041] Specifically, in the initial state, the blocking plate 24 will have a tendency to turn outward under the torsion of the torsion spring shaft 243, and the blocking plate 24 is limited and blocked by the clamping seat 241, so that the blocking plate 24 remains in the vertical state, at this time the can cover will be able to pass smoothly under the blocking plate 24. When the can cover is turned over, the blocking plate 24 will overcome the torsion of the torsion spring shaft 243 and rotate into the accommodation groove 242, at this time the blocking plate 24 will remain in the horizontal state and effectively block the rear can cover.

[0042] As shown in Figure 6 , the receiving conveying table 4 extends upward at one end to provide a limiting sleeve 41, the limiting sleeve 41 is located directly below the turnover plate 31, and the inner diameter of the limiting sleeve 41 is greater than the diameter of the can cover.

[0043] Specifically, after the can cover is turned over 180° with the turnover plate 31, the can cover will remain face up and be located directly above the limiting sleeve 41, when the air extraction is stopped, the can cover will fall into the limiting sleeve 41 under the action of its own gravity, and the limiting and guiding action of the limiting sleeve 41 can effectively prevent the can cover from deviating during the falling process, so that the turned over can cover can be smoothly dropped into the receiving conveying table 4 and remain face up for forward conveying.

[0044] As shown in Figure 6 and Figure 7 , the discharging track 5 includes an inclined portion 51 and a vertical portion 52, the top end of the inclined portion 51 is smoothly provided with a first feeding port 511, the first feeding port 511 is in transition connection with the end of the screening conveying table 2, the side wall of the inclined portion 51 is smoothly provided with a second feeding port 512, the second feeding port 512 is in transition connection with the end of the receiving conveying table 4, and the vertical portion 52 is provided at the bottom with a discharging port 521, and the discharging conveying table 6 is arranged at the bottom of the discharging port 521.

[0045] Specifically, when the can cover enters the discharging track 5, the limiting and guiding of the discharging track 5 to the can cover enables the can cover to always remain correctly oriented and pass through the inclined portion 51 and the vertical portion 52 in turn, and can be converted from a horizontal state to a vertical state. The standing can cover will fall on the discharging conveying table 6 and be conveyed out from the discharging port 521 along the discharging conveying table 6.

[0046] As shown in Figure 7 , the discharging conveying table 6 is fixedly provided at both sides with limiting guide rails 61 for aligning and limiting the can cover, and the discharging conveying table 6 is fixedly provided above with an electricity connecting sliding rail 62, and the electricity connecting sliding rail 62 is linearly and slidingly installed with a stacking blocking piece 63.

[0047] As shown in Figure 8As shown, the stacking stopper 63 includes a pressing portion 631 abutting against the side wall of the can lid, a connecting rod 632 with a bottom end fixedly connected with the pressing portion 631 and a top end fixedly connected with an electric slide 633 linearly slidingly installed on the power connection rail.

[0048] Specifically, when the standing can lids are conveyed out of the discharge port 521, the limiting guide rail 61 limits the can lids by surrounding the circumferential outer wall of the can lids, and the pressing portion 631 abuts against the end face of the frontmost can lid, so that the can lids are continuously conveyed out of the discharge conveying table 6 from the rear end, thereby enabling the can lids to be gradually stacked and automatically aligned, and the electric slide 633 linearly slides along the power connection rail, so that the aligned can lids are conveyed along the discharge conveying table 6 in an orderly manner.

[0049] As shown in Figure 1 and Figure 2 As shown, the two sides of the upper end of the feeding conveying table 1 are provided with guide plates 11 inclinedly arranged, the end portions of the guide plates 11 are provided with limiting plates 12, the limiting plates 12 on the two sides form a channel for the can lids to pass in an aligned manner, and the inner walls on the two sides of the screening conveying table 2 are provided with convex plates 21, the convex plates 21 and the screening conveying table 2 form limiting tracks to constrain the longitudinal movement of the can lids.

[0050] Specifically, the guide plates 11 and the limiting plates 12 enable the can lids to be arranged one by one into the screening conveying table 2, so that the conveying process is orderly performed. When the can lids enter the screening conveying table 2, the convex plates 21 limit and block the two sides of the can lids from the upper end, so that the can lids can be effectively prevented from jumping during the conveying process.

[0051] The working principle of the present application is as follows: Figures 1-8As shown, in use, the punched can cover falls on the feeding conveying table 1, and is conveyed forward to the screening conveying table 2 through the feeding conveying table 1, when the can cover passes through the turnover plate 31, the can cover is visually detected by the industrial camera 23 to determine whether it is face up, when the can cover is face up, the turnover assembly 3 does not work, at this time the can cover on the turnover plate 31 will continue to be conveyed forward under the conveying of the rear can cover, when the can cover is back up, the air suction pipe 34 starts to suck air according to the detection signal, since the air suction pipe 34 is connected with the air cavity 311 through the hollow shaft 33 and the air pipe 313, the negative pressure air nozzle 312 continuously sucks air and generates negative pressure suction force at the upper end of the turnover plate 31 to adsorb the can cover. During the air suction process, the airflow continuously flowing in the air suction pipe 34 will drive the fan blade 345 to rotate, the fan blade 345 will drive the pivot shaft 344 to rotate synchronously, the pivot shaft 344 will drive the torsional spring shaft 243 to rotate through the transmission belt 244, so that the blocking plate 24 can realize rotation to block the rear can cover to avoid affecting the turnover process. The turnover motor 35 drives the transmission tooth 321 to rotate through the driving tooth 351, the transmission tooth 321 drives the turnover plate 31 to rotate 180° through the rotating shaft 32, so that the can cover is face up and falls on the receiving conveying table 4 to continue to be conveyed forward, so that the automatic detection and turnover process of the can cover can be realized in the can cover conveying and feeding process. The can cover originally face up will be conveyed into the discharging track 5 through the screening conveying table 2, and the can cover face up after turnover will be conveyed into the discharging track 5 through the receiving conveying table 4, and the discharging track 5 is used for limiting and guiding the can cover, so that all the can covers can always maintain correct orientation in the discharging track 5 and be converted from a horizontal state to a vertical state, the can cover standing up will gradually be stacked and automatically aligned along the discharging conveying table 6, so that the integrated conveying process of the can cover feeding, detection, turnover, discharging and discharging is realized.

[0052] The above describes one embodiment of the present application in detail, but the above description is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent scope of the present application.
