The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0036] like Figure 1-7 As shown, a rotary table roller comprises a roller body 1 and a lifting and rotating mechanism 2, wherein the roller body 1 comprises a roller frame 3, a long roller 41 mechanism 4 and a short roller mechanism 5, wherein the roller frame 3 is provided with a posture conversion station 100 near the feeding side, the short roller mechanism 5 is provided on the posture conversion station 100, and the long roller 41 mechanism 4 is provided on the non-posture conversion station 100 of the roller frame 3;

[0037] The long roller 41 mechanism 4 comprises a plurality of long rollers 41 connected to the roller table frame 3 at both ends through roller shafts;

[0038] The short roller mechanism 5 includes a plurality of short roller assemblies 51, and the short roller assembly 51 includes a coaxial upper short roller 511 and a lower short roller 512. The ends of the upper short roller 511 and the lower short roller 512 that are far away are connected to the roller frame 3 through a roller shaft, and the ends that are close to each other are respectively connected to the upper short roller mounting plate 10 and the lower short roller mounting plate 20 through a roller shaft. The upper short roller mounting plate 10 and the lower short roller mounting plate 20 are connected to the roller frame 3. The lifting and rotating mechanism 2 is arranged between the upper short roller mounting plate 10 and the lower short roller, and the lifting and rotating mechanism 2 is used to lift and rotate the workpiece;

[0039] The roller table body 1 further comprises a roller driving assembly 6 for driving the long roller 41, the upper short roller 511 and the lower short roller 512 to rotate synchronously;

[0040] A limiting mechanism 8 is provided on the unloading side of the roller frame 3, and the limiting mechanism 8 is used to correct the workpiece that is offset to one side of the roller.

[0041] In this embodiment, the roller drive assembly 6 drives the long roller 41, the upper short roller 511 and the lower short roller 512 to rotate synchronously, driving the workpiece placed on the roller body 1 to move from the loading direction to the loading direction. When the workpiece flows into the posture conversion station 100, the lifting and rotating mechanism 2 drives the workpiece to rise, and after rising, drives the workpiece to rotate 90 degrees to perform posture conversion. After the posture conversion is completed, the lifting and rotating mechanism 2 descends, and then the workpiece is driven by the upper short roller 511 and the lower short roller 512 to flow out of the posture conversion station 100; in addition, because the workpiece is biased to one side of the roller body 1 as a whole after the posture conversion, it is easy to contact and scratch the roller frame 3. Damage, therefore, the position of the workpiece on the roller body 1 is corrected by the limiting mechanism 8 so that it is located in the center of the roller body 1;

[0042] The above structure realizes rotating the workpiece 90 degrees to change its posture when it reaches the set position while conveying the workpiece, and automatically correcting the working position after the posture change. It is efficient, low-cost, and convenient for standardized production, thereby improving the yield rate of the workpiece.

[0043] In this embodiment, the lengths of the upper short roller 511 and the lower short roller 512 are the same or different, that is, the lifting and rotating mechanism 2 can be placed in the middle of the roller frame 3 or offset to one side of the roller frame 3 according to the actual workpiece specifications or processing conditions.

[0044] Further, such as Figure 3 , 4 As shown in FIG. 5 , in order to realize driving the first sprocket 30, the upper short roller 511 and the lower short roller 512 rotate synchronously with high stability, a transmission structure design of a chain 64 sprocket is adopted, and the first sprocket 30 is respectively provided at both ends of the cylinder 41 of the long roller, and the second sprocket 40 is respectively provided at the ends away from the cylinder of the upper short roller 511 and the cylinder of the lower short roller 512;

[0045] The roller drive assembly 6 includes a drive motor 61, a drive gear 62, a transmission gear 63 and a chain 64. The drive motor 61 is connected to the middle of the roller frame 3, the drive gear 62 is connected to the drive shaft of the drive motor 61, and the transmission gear 63 is rotatably arranged at both ends of the roller frame 3;

[0046] The two ends of the chain 64 are meshed and connected with the transmission gear 63 , the lower part is meshed and connected with the driving gear 62 , and the upper part is meshed and connected with the first sprocket 30 and the second sprocket 40 .

[0047] In this embodiment, the first sprocket 30 cannot rotate relative to the body of the long roller 41, and the second sprocket 40 cannot rotate relative to the upper short roller 511 and the lower short roller 512, that is, when the chain 64 moves, it can drive the long roller 41, the upper short roller 511 and the lower short roller 512 to rotate around the axis of their respective roller shafts.

[0048] Further, such as Figure 6 , 7 As shown, in order to realize the lifting and rotation of the workpiece, the lifting and rotating mechanism 2 includes a lifting component 21 and a rotating component 22 , the lifting component 21 is connected to the roller frame 3 , and the rotating component 22 is connected to the lifting component 21 .

[0050] Further, such as Figure 7 As shown, in order to improve the smoothness of the lifting and lowering of the rotating assembly 22, the plurality of guide assemblies 7 include a guide sleeve 71 connected to the roller frame 3, and a guide rod 72 slidably sleeved with the guide sleeve 71, and one end of the guide rod 72 is connected to the rotating assembly 22.

[0051] Further, such as Figure 1 , 6 As shown in 7, in order to achieve smooth rotation of the workpiece after lifting, the rotating component 22 includes a reduction motor 221 connected to the driving end of the lifting cylinder 211, the driving shaft of the reduction motor 221 is perpendicular to the workpiece, and the rotating component 22 also includes a rotating bracket 222 connected to the driving shaft of the reduction motor 221; one end of the guide rod of the guide component 7 is connected to the reduction motor 221.

[0052] Further, such as Figure 6 As shown, in order to increase the contact area between the rotating bracket 222 and the workpiece and improve the stability of the lifting and rotation of the workpiece without interfering with the rotation of the rollers, the rotating bracket 222 also includes an extended support section 222a extending around the outer side of the rotating bracket 222, and the extended support section 222a is placed between two adjacent upper short rollers 511 and / or between two adjacent lower short rollers 512.

[0053] Further, such as Figure 6 , 7 As shown, in order to accurately and automatically control the rotation angle of the rotating bracket 222, the rotating component 22 also includes a rotating sensing block 223 and a proximity switch 224. The rotating sensing block 223 is a cross structure. The end of the driving shaft of the reduction motor 221 away from the rotating bracket 222 is connected to the rotating sensing block 223, and the proximity switch 224 is located on one side of the rotating sensing block 223. The proximity switch 224 is electrically connected to the reduction motor 221. When the rotating sensing block 223 rotates, the end approaches and triggers the proximity switch 224 to control the reduction motor 221 to stop rotating.

[0054] Further, such as Figure 1 , 2 As shown in Figure 3, in order to effectively and reliably correct the position of the workpiece after the posture conversion, the limiting mechanism 8 includes limiting components 81 relatively arranged on both sides of the roller frame 3, and the two limiting components 81 include a limiting cylinder 811 and a limiting plate 812 connected to the driving end of the limiting cylinder 811, and the two limiting cylinders 811 are driven synchronously; when working, the width of the workpiece passing through the roller body 1 is changed by the two limiting plates 812, and the workpiece is placed in the middle of the roller body 1 under the drive of the long roller 41 mechanism 4 and the short roller mechanism 5.

[0055] Further, such as Figure 1 As shown, in order to accurately control the drive of the lifting and rotating mechanism 2 and prevent the workpiece from being lifted too early or too late, which would affect the accuracy of the posture conversion, the roller frame 3 is located on one side of the lifting and rotating mechanism 2 and is provided with a photoelectric sensor 9 for sensing the workpiece, and the photoelectric sensor 9 is electrically connected to the lifting and rotating mechanism 2.

[0056] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
