[0031] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0032] As attached Figure 1 As shown, a rotary reversing roller device includes a transport platform 1, a transmission mechanism 2, a base frame 3, a rotating component 4, and a detection component 6.

[0033] As attached Figure 2 and attached Figure 3 As shown, the transport platform 1 is rectangular in shape, and the four corners of the transport platform 1 are not right angles. Here, the four corners of the transport platform 1 are 45° angles. Two relatively parallel support frames 11 are installed on both sides of the transport platform 1. The transmission mechanism 2 includes a chain assembly 21 and a servo motor 22.

[0034] The servo motor 22 is mounted on the side wall of one of the support frames 11, referred to here as the first support frame 111, and the other support frame 11 parallel to it is referred to as the second support frame 112. The servo motor 22 is located on the side of the first support frame 111 facing away from the second support frame 112, and the output shaft of the servo motor 22 is equipped with a drive gear 221.

[0035] A rotating roller 12 is installed between the first support frame 111 and the second support frame 112. There are multiple rotating rollers 12, which are evenly spaced and arranged in parallel. The two ends of the rotating rollers 12 are rotatably connected to the first support frame 111 and the second support frame 112, respectively. A transmission gear 121 is installed on the end of each rotating roller 12 facing the first support frame 111. A linkage gear 122 is also installed on one of the rotating rollers 12. The linkage gear 122 is located on the side of the transmission gear 121 facing the first support frame 111 and is located below the drive gear 221.

[0036] The chain assembly 21 comprises a driving chain 211 and a transmission chain 212. The driving chain 211 passes through the linkage gear 122 and the driving gear 221 respectively and is in meshing transmission with the linkage gear 122 and the driving gear 221 respectively. The transmission chain 212 passes through the linkage gears 122 on the rotating rollers 12 in sequence and is in meshing transmission with the linkage gears 122 respectively.

[0037] The four detection assemblies 6 are vertically fixed above the support frames 11. Two detection assemblies 6 on each of the two support frames 11 form a group. The two detection assemblies 6 in the same group are in the same horizontal plane in the axial direction of the rotating roller 12. The detection assembly 6 comprises a fixed rod 61 and an infrared sensor 62. The fixed rod 61 is provided with a sliding groove 611 in the installation direction of the fixed rod 61. The infrared sensor 62 is in sliding connection with the sliding groove 611 in the installation direction of the fixed rod 61. The infrared sensor 62 is used to detect whether the conveying position of the product is in place, so as to ensure that the product is conveyed to the set position under the action of the rotating roller 12 and the chain assembly 21.

[0038] As shown in FIGS. 1 and 2, the transport table 1 is provided with a first fixed plate 14. The first fixed plate 14 is located in the middle of the transport table 1. A first fixed hole 141 is formed in the middle of the first fixed plate 14. Figure 4 Figure 5 As shown in FIGS. 1 and 2, the transport table 1 is provided with a first fixed plate 14. The first fixed plate 14 is located in the middle of the transport table 1. A first fixed hole 141 is formed in the middle of the first fixed plate 14.

[0039] The base frame 3 is located below the transport table 1 and is parallel to the transport table 1. Four support legs 31 are respectively arranged around the base frame 3 and are used to support and fix the base frame 3.

[0040] The driving motor 51 is arranged on the base frame 3 and is parallel to the base frame 3. The output shaft of the driving motor 51 is perpendicular to the base frame 3. A rotating gear 52 is arranged on the output shaft of the driving motor 51.

[0041] The second fixed plate 32 is arranged on the base frame 3 and is located above the driving motor 51. The second fixed plate 32 is located in the middle of the base frame 3. A second fixed hole 321 is formed in the middle of the second fixed plate 32.

[0042] The rotating member 4 comprises a first rotating support 41 and a second rotating support 42. The first rotating support 41 is annular. The side of the first rotating support 41 away from the base frame 3 is fixedly connected with the first fixed plate 14. The inner diameter of the first rotating support 41 is greater than the outer diameter of the first fixed hole 141. A vertical rack 411 is arranged on the inner side wall of the first rotating support 41. The rotating gear 52 on the output shaft of the driving motor 51 passes through the second fixed hole 321 and is in meshing transmission with the rack 411.

[0043] ​The second rotating support 42 is annular. The side of the second rotating support 42 facing away from the transport table 1 is fixedly connected to the second fixed plate 32. The inner diameter of the second rotating support 42 is larger than the outer diameter of the second fixed hole 321, and the inner sidewall of the second rotating support 42 abuts against and is fixed to the outer sidewall of the first rotating support 41. A ball bearing for the first rotating support 41 to rotate is installed inside the second rotating support 42. The rotating part 4 here is a common technical part in the art and will not be described in detail here.

[0044] A gap is left between the bottom surface of the first rotating support 41 and the top surface of the second fixed plate 32 to prevent the first rotating support 41 from coming into contact with the second fixed plate 32, thereby reducing the risk of increased resistance when the second fixed plate 32 rotates the first rotating support 41.

[0045] As attached Figure 2 As shown, through-beam sensors 15 are installed on both sides of the transport platform 1, and multiple sensing plates 33 that cooperate with the through-beam sensors 15 are provided around the base frame 3. The through-beam sensors 15 are located above the sensing plates 33. Through the cooperation of the through-beam sensors 15 and the sensing plates 33, it can be used to detect whether the transport platform 1 has been reversed to the correct position, ensuring that the transport platform 1 can transport the product only after it has been reversed to the correct position, thus improving the safety performance of product transportation.

[0046] The working principle of this embodiment:

[0047] After the product is placed on the top surface of the rotating roller 12, the servo motor 22 is started. The output shaft of the servo motor 22 drives the drive chain 211 to drive the rotating roller 12 equipped with the linkage gear 122 to rotate. The rotating roller 12 equipped with the linkage gear 122 drives multiple rotating rollers 12 to rotate simultaneously through the transmission chain 212, thereby conveying the product on the rotating roller 12 in the X direction.

[0048] Two sets of infrared sensors 62 on the two support frames 11 detect the conveying of the product. When the product is conveyed to the set position on the rotating roller 12, the drive motor 51 is started. The drive motor 51 can drive the rotating gear 52 to rotate, which drives the first rotating support 41 meshing with it to rotate synchronously, thereby driving the transport table 1 fixedly connected to the first rotating support 41 to rotate, so as to realize the reversal of the product placed on the transport table 1. At the same time, the through-beam sensor 15 on the transport table 1 and the sensing plate 33 cooperate with each other. After the transport table 1 is reversed, the servo motor 22 is started, so as to convey the product on the rotating roller 12 in the Y direction.

[0049] When the product is being transported, the drive motor 51 can drive the rotating part 4 to transport the product in multiple directions, and the servo motor 22 is located below the transport table 1 to drive the transport table 1 to rotate, so that the conveying device has a high space utilization rate on the production line.

[0050] The embodiments are only illustrative of the present application, and are not intended to limit the present application. Those skilled in the art can make modifications to the embodiments according to the present application without creative contribution, and the modifications are protected by the patent law as long as they are within the scope of the present application.
