DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1As shown, a canned beer transport device according to an embodiment of the present invention comprises a support platform 1, a transmission belt 11 is installed inside the support platform 1, guide plates 2 are arranged on both sides above the transmission belt 11, a plurality of rollers are rotatably connected to the guide plates 2 near the center of the transmission belt 11, an adjustment component for adjusting the distance between the guide plates 2 is arranged above the guide plates 2, and a lifting component for handling fallen canned beer is arranged above the transmission belt 11;

[0033] The production of canned beer requires multi-step processing. A transportation device is required to transport the canned beer to the next processing station. During transportation, the transmission belt 11 is started to roll and the canned beer is placed on the top of the transmission belt 11. The rolling of the transmission belt 11 can drive the canned beer to be transported to other stations. During the transportation, the guide plate 2 can block both sides of the transmission belt 11 and guide the canned beer at the same time. When the transmission belt 11 transports the canned beer to a single processing station, the distance of the guide plate 2 is adjusted by the adjustment component, so that the canned beer at the top of the transmission belt 11 can be changed from multiple conveying to single conveying. The canned beer can be automatically transported to improve the processing efficiency. The canned beer that falls during the transportation process can be lifted up by the lifting component to prevent the canned beer from falling down and affecting the transportation.

[0034] like Figure 1 to Figure 2 As shown, the adjustment component includes support columns 3 fixed on both sides of the support platform 1, a first support plate 31 is fixed between the two support columns 3, guide grooves 32 are opened on both sides of the first support plate 31, and second motors 33 are installed at both ends of the first support plate 31, and a first threaded rod 331 is fixed to the end of the rotating shaft of the second motor 33, and the first threaded rod 331 runs through the inside of the guide groove 32, and a moving sleeve 34 is sleeved on the outside of the first support plate 31, and a slider 341 is fixed inside the moving sleeve 34, and the slider 341 constitutes a sliding structure inside the guide groove 32, and the first threaded rod 331 is threadedly connected to the slider 341, and the bottom end of the moving sleeve 34 is fixedly connected to the top end of the guide plate 2 through a fixed column;

[0035] When the spacing between the guide plates 2 needs to be adjusted, the second motor 33 is started to drive the first threaded rod 331 to rotate. At this time, the first threaded rod 331 drives the slider 341 to slide inside the guide groove 32, and the slider 341 drives the movable sleeve 34 to move outside the first support plate 31. The movable sleeve 34 drives the guide plate 2 to move. At this time, the spacing between the guide plates 2 can be adjusted, and the number of canned beer that can pass between the guide plates 2 at a time can be adjusted.

[0036] like Figures 1 to 3As shown, the adjustment assembly also includes a connecting plate 21 arranged at one end of the guide plate 2, a movable plate 22 is arranged at the end of the connecting plate 21 away from the guide plate 2, a connecting column 222 is fixed at the top and bottom ends of the movable plate 22, a fixed gear 221 is fixed at the end of the connecting column 222 away from the movable plate 22, a connecting column 222 and a fixed gear 221 are also fixed at the top and bottom ends of the guide plate 2 close to the connecting plate 21, connecting blocks 211 are fixed at the top and bottom ends of both sides of the connecting plate 21, the connecting blocks 211 are sleeved on the outside of the connecting columns 222, and the two ends inside the connecting plate 21 are rotatably connected with a transmission shaft 24, and the top end of the transmission shaft 24 A steering gear 241 is fixed to the bottom end, the steering gear 241 is meshed with the fixed gear 221, a worm gear 242 is fixed to the middle of the transmission shaft 24, a first motor 23 is installed on the side of the connecting plate 21 close to the support column 3, a connecting rod 231 is arranged below the first motor 23, a transmission gear 232 is fixed to the middle of the connecting rod 231, a gear is fixed to the end of the rotating shaft of the first motor 23, the gear is meshed with the transmission gear 232, screws 233 are fixed to both sides of the connecting rod 231, the connecting rod 231 is rotatably connected to the connecting plate 21 through a support block, and the screw 233 is meshed with the worm gear 242;

[0037] In some production steps, it is necessary to process canned beer individually, and at this time, the shape of the guide plate 2 needs to be adjusted. During the adjustment process, the first motor 23 is started to rotate, and the first motor 23 drives the transmission gear 232 to rotate through the gear, and the transmission gear 232 drives the connecting rod 231 to rotate, and the connecting rod 231 drives the screws 233 at both ends to rotate, and the screw 233 drives the worm gear 242 to rotate, and the worm gear 242 drives the transmission shaft 24 to rotate, and the transmission shaft 24 drives the steering gear 241 to rotate. At this time, the fixed gear 221 at one end of the guide plate 2 is in a fixed state, and the steering gear 241 rotates to drive the connecting plate 21 to flip, and at the same time, the steering gear 241 at the other end drives the fixed gear 221 to rotate, and the fixed gear 221 drives the movable plate 22 to flip in the opposite direction through the connecting column 222. At this time, the movable plate 22 can always remain parallel to the guide plate 2, and the distance between the movable plates 22 is shortened to only be able to hear a single can of beer, and the distance between the guide plates 2 remains unchanged. At this time, the canned beer cans can be transported individually under the drive of the transmission belt 11.

[0038] like Figures 1 to 4 As shown, the lifting assembly includes a support frame 4 fixed on the top of the support platform 1, one side of the support frame 4 is fixedly connected to the first support plate 31, a camera 41 is arranged below the support frame 4, a moving frame 42 is fixed to the side of the support frame 4 away from the camera 41, a moving block 422 is slidably connected inside the moving frame 42, an electric telescopic rod 43 is fixed below the moving block 422, a shell 44 is fixed to the bottom end of the electric telescopic rod 43, and a fixing clamp 45 is arranged at the bottom end of the shell 44;

[0039] When the transmission belt 11 is transporting canned beer, the beer may fall down when it is placed on the top of the transmission belt 11 or fall down during the transportation process. The fallen canned beer will affect the transportation of the transmission belt 11, so it is necessary to pick up the fallen canned beer. When the canned beer moves at the top of the transmission belt 11, it will pass by the camera 41. At this time, the camera 41 takes pictures of the top of the transmission belt 11. Through the taken pictures, it can be analyzed whether there is a canned beer that has fallen down. When a fallen can of beer is detected, the moving block 422 moves inside the moving frame 42 to the position behind the canned beer that needs to pass. Before the fallen beer arrives, the electric telescopic rod 43 is started to drive the shell 44 to move downward. After the fallen beer arrives, the fixed clamp 45 under the shell 44 can clamp the beer to pick it up. After it is picked up, the electric telescopic rod 43 drives the shell 44 to rise.

[0040] like Figures 1 to 4 As shown, a displacement motor 421 is installed at one end of the moving frame 42, a second threaded rod 423 is fixed to the end of the rotating shaft of the displacement motor 421, and the second threaded rod 423 is threadedly connected to the moving block 422;

[0041] When the moving block 422 is moved, the displacement motor 421 is started to drive the second threaded rod 423 to rotate, and the second threaded rod 423 drives the moving block 422 to move inside the moving frame 42, so that the position of the moving block 422 can be adjusted according to the position of the fallen beer.

[0042] like Figures 1 to 5 As shown, a flip plate 411 is fixed to the top of the camera 41, and the flip plate 411 is rotatably connected to the inside of the support frame 4. A third motor 412 is installed inside the support frame 4, and the end of the shaft of the third motor 412 is fixedly connected to the end of the shaft of the flip plate 411;

[0043] When the camera 41 takes a picture of the canned beer at the top of the transmission belt 11, the photographing area is small, which may cause some canned beer to fail to be detected. At this time, the third motor 412 is started to drive the flip plate 411 to flip. When the flip plate 411 flips, it can drive the camera 41 to flip. The flipping of the camera 41 can adjust its shooting position, so that the shooting range of the camera 41 can be larger.

[0044] like Figures 1 to 5 As shown, the maximum flip angle of the flip plate 411 is 90°;

[0045] When the third motor 412 drives the flip plate 411 to flip, the third motor 412 only drives the flip plate 411 to flip 90° each time. After flipping, the third motor 412 drives the flip plate 411 to rotate 90° in the opposite direction, so that the camera 41 reciprocates to shoot the top of the transmission belt 11.

[0046] like Figures 1 to 7 As shown, a steering motor 441 is installed at the top of the housing 44, and an inner gear disc 444 is rotatably connected to the bottom of the housing 44. Three planetary gears 443 are meshedly connected inside the inner gear disc 444. The tops of the planetary gears 443 are rotatably connected to the housing 44 through support blocks, and the third output gears 442 are meshedly connected between the planetary gears 443. The end of the rotating shaft of the steering motor 441 is fixedly connected to the top of the third output gear 442.

[0047] When straightening the canned beer, the angle at which the canned beer falls will be different. At this time, the angle of the fixing clamp 45 is adjusted by analyzing the falling angle of the canned beer, and the steering motor 441 is started to drive the third output gear 442 to rotate, and the third output gear 442 drives the planetary gear 443 to rotate, and the planetary gear 443 drives the external inner gear plate 444 to rotate. At this time, the inner gear plate 444 can drive the fixing clamp 45 to adjust the angle. By setting the planetary gear 443 and the inner gear plate 444, the weight of the fixing clamp 45 driven by the steering motor 441 can be more evenly distributed on the surface of the planetary gear 443, which can increase the service life.

[0048] like Figures 1 to 8 As shown, a second support plate 455 is fixed to the bottom end of the inner gear disc 444 through a rotating shaft, and a fixing clamp 45 is hinged on both sides of the second support plate 455. Two clamping gears 456 are fixed to the top of the fixing clamp 45, and a connecting shaft 451 is fixed between the clamping gears 456. The connecting shaft 451 runs through the inside of the second support plate 455, and coil springs 452 are fixed to both ends of the connecting shaft 451. The outer side of the coil spring 452 is fixedly connected to the second support plate 455. A clamping motor 453 is installed inside the second support plate 455, and a fourth output gear 454 is fixed to the end of the rotating shaft of the clamping motor 453. The fourth output gear 454 is meshed and connected with one of the clamping gears 456.

[0049] When clamping the canned beer, the clamping motor 453 is started to drive the fourth output gear 454 to rotate, and the fourth output gear 454 drives the clamping gear 456 to rotate. At this time, the two fixing clamps 45 are flipped outward, and the turning drives the coil spring 452 to tighten through the connecting shaft 451. When the fallen canned beer is placed between the fixing clamps 45, the clamping motor 453 is stopped. At this time, the elastic force of the coil spring 452 drives the connecting shaft 451 to reset, and the connecting shaft 451 drives the two fixing clamps 45 to clamp the canned beer. In this way, the canned beer is clamped by the elastic force of the coil spring 452, and the clamping force is uniform, which can prevent the canned beer from being deformed due to excessive force during the clamping process.

[0050] like Figures 1 to 9As shown, a clamp block 46 is rotatably connected to the lower part of the fixing clamp 45 near the second support plate 455, a rotating rod 461 is fixed to one end of the clamp block 46 near the fixing clamp 45, the rotating rod 461 is rotatably connected to the inside of the fixing clamp 45, and a movable groove 463 is provided at one end of the fixing clamp 45 away from the clamp block 46, a tension spring 462 is fixed to the top of the rotating rod 461, and the top of the tension spring 462 is fixedly connected to the fixing clamp 45;

[0051] When the fixing clamp 45 clamps the can of beer, the clamp block 46 will be stuck near the outer open end of the can of beer. The interior of the clamp block 46 is provided with a groove body that matches the outer part of the can of beer. After clamping the can of beer, the electric telescopic rod 43 pulls up the fixing clamp 45. At this time, under the gravity of the can of beer itself, its bottom will flip downward 90°, and the clamp block 46 will flip along with the can of beer. At the same time, the clamp block 46 pulls the tension spring 462 through the rotating rod 461, and then the fixing clamp 45 opens to release the can of beer and place it on the top of the transmission belt 11. Then the tension spring 462 pulls the rotating rod 461 to reset, and the rotating rod 461 drives the clamp block 46 to recover, so that the can of beer can can be straightened by its own weight.
