Description

Technical Field

[0001] This utility model relates to the field of tire conveying equipment, specifically to an automatic tire turning device. Background Technology

[0002] In the rubber tire production process, tire specifications, models, weight, uniformity, and dynamic balance need to be tested. The results of each test are marked on the tire sidewall with a barcode or circular code. When measuring the next parameter, the previous barcode or circular code needs to be identified to read the measured results and tire management information. However, these barcodes or circular codes are not fixed on the side of the tire. Furthermore, tires are sometimes transported from previous processes and sometimes randomly placed on the production line by hand. When manually placing tires, they are randomly placed on the conveyor line. Sometimes, when coding or reading the tire codes, it is necessary to rotate the tire 180° according to the position of the barcode or circular code. In the past, tire rotation was done manually, which was not only inefficient but also affected the accuracy of the printed markings due to changes in the tire's angle and position after rotation.

[0037] This embodiment provides an automatic tire-turning device, which is mainly used to carry tires and assist in tire inspection.

[0038] like Figures 1 to 4 As shown, the automatic tire turning device includes a frame 100, a support conveying device 200, a drive device 300, and a tire pressing device 400.

[0039] The supporting conveying device 200 includes a supporting frame 210, a first conveying roller assembly 220, and a second conveying roller assembly 230.

[0040] The two sides of the support frame 210 are rotatably connected to the frame 100 via shaft assemblies 110;

[0041] The first conveying roller assembly 220 is connected to the upper end of the support frame 210, and the second conveying roller assembly 230 is connected to the lower end of the support frame 210. A channel for accommodating the tire is formed between the first conveying roller assembly 220 and the second conveying roller assembly 230, and the height of the channel is greater than the thickness of the tire. That is, the tire is conveyed into the channel, and the second conveying roller assembly 230 moves the tire to a preset position.

[0042] The drive unit 300 is connected to the shaft assembly 110 and is used to drive the support frame 210 to rotate by driving the shaft assembly 110; thereby driving the tires in the channel to rotate synchronously.

[0043] The tire pressing device 400 is connected to the upper end of the support frame 210. The tire pressing device 400 includes a telescopic drive device 410 and a pressing member 420 connected to each other. The pressing member 420 is located in the channel. The telescopic drive device 410 drives the pressing member 420 to move along the height direction of the channel to press or release the tire.

[0044] In practical applications, when the tire moves to a preset position in the channel (for example, the preset position can be the middle of the channel), the telescopic drive device 410 is activated, and the pressing member 420 moves downward to press against the upper end face of the tire; then the drive device 300 drives the support frame 210 to rotate through the drive shaft assembly 110; thereby achieving the automatic rotation function of the tire. The rotation angle of the support frame 210 can be set to 0-180 degrees. After the support frame 210 drives the tire to rotate 180 degrees, the telescopic drive device 410 is activated again, and the pressing member 420 moves in the opposite direction to release the tire. At this time, the tire contacts the first conveying roller assembly 220, which is used by workers to inspect the tire. After the inspection is completed, the tire can be transported to the equipment of the next process through the first conveying roller assembly 220.

[0045] In a preferred embodiment, the support frame 210 includes a first frame 211, a second frame 212, and a plurality of support columns 213; the first frame 211 is located above the second frame 212, and the first frame 211 and the second frame 212 are connected by the plurality of support columns 213; preferably, the first frame 211 and the second frame 212 can be configured as rectangles.

[0046] The first conveyor roller assembly 220 and the tire pressing device 400 are connected to the inner wall of the first frame 211; the second conveyor roller assembly 230 is connected to the inner wall of the second frame 212.

[0047] In a preferred embodiment, bearings with mounting brackets are provided on both sides of the frame 100, and the shaft assembly 110 passes through the bearings with mounting brackets. The drive device 300 is mounted on the frame 100. In this embodiment, the drive device 300 can be a hollow shaft geared motor, with one shaft assembly 110 connected to the power output end of the hollow shaft geared motor for driving the shaft assembly 110 to rotate; of course, the drive device 300 can also be a servo motor, which is connected to the shaft assembly 110 for driving the shaft assembly 110 to rotate.

[0048] As a preferred embodiment, the tire pressing device 400 also includes a support plate 430, which is connected to the first frame 211 via a connecting frame. The telescopic drive device 410 is fixed on the support plate 430, and the support plate 430 is provided with a through hole for the telescopic rod to pass through. The telescopic rod of the telescopic drive device 410 is connected to the pressing member 420 and is used to drive the pressing member 420 to move.

[0049] The telescopic drive device 410 preferably uses a cylinder, and a pressure regulating valve is connected to the cylinder's pipeline. When testing different sizes of tires, the air pressure of the pressure regulating valve is adjusted to make the cylinder adapt to the pressure corresponding to different sizes of tires.

[0050] like Figure 5As shown, in a preferred embodiment, the pressing component 420 includes a first pressing plate 421, a second pressing plate 422, and auxiliary pressing plates 423; wherein the first pressing plate 421 and the second pressing plate 422 are cross-connected; multiple auxiliary pressing plates 423 are respectively located on both sides of the first pressing plate 421 and are cross-connected to the first pressing plate 421. The first pressing plate 421, the second pressing plate 422, and the auxiliary pressing plates 423 apply pressure to the tire surface, thus pressing the tire down to allow it to rotate without causing wobbling or displacement.

[0051] As a preferred embodiment, the tire pressing device 400 also includes a guiding mechanism, which includes a plurality of guide rods 440, a linear bearing 450 and a timing frame 460;

[0052] Multiple linear bearings 450 are fixed on a support plate 430. The support plate 430 has corresponding through holes for the guide rods 440 to pass through. The positions of the through holes correspond one-to-one with the positions of the linear bearings 450. The multiple linear bearings 450 are distributed in the circumferential direction of the telescopic drive device 410. The guide rods 440 pass through the corresponding linear bearings 450. The upper ends of the multiple guide rods 440 are respectively connected to the synchronous frame 460, and the lower ends of the multiple guide rods 440 are respectively connected to the pressing member 420. The synchronous frame 460 has through holes for the telescopic drive device 410 to pass through. In this way, when the synchronous frame 460 moves under the drive of the guide rods 440, it will not cause positional interference to the telescopic drive device 410.

[0053] As a preferred embodiment, sensors 470 are provided at both ends of the first pressure plate 421 or the second pressure plate 422 along the length direction. For example, through-beam photoelectric sensors can be used. The sensors 470 are located on the bottom surface of the corresponding pressure plate and are used to assist the control system in detecting the height position of the tire.

[0054] The automatic tire-turning device provided in this embodiment also includes a tire-stop positioning rod 500. The tire-stop positioning rod 500 is located on one side of the channel and is connected to the support frame 210. Specifically, the tire-stop positioning rod 500 can be connected to the first frame 211, or to the second frame 212, or to both the first frame 211 and the second frame 212 at the same time.

[0055] As a preferred embodiment, the first conveying roller assembly 220 can be a roller mill; specifically, the first conveying roller assembly 220 includes a plurality of first conveying rollers 221, a first transmission assembly 222, and a first drive assembly 223. The plurality of first conveying rollers 221 are rotatably connected to the first frame 211 respectively. The plurality of first conveying rollers 221 are connected to each other through corresponding first transmission assemblies 222. The first transmission assembly 222 can adopt a gear and chain transmission structure, that is, a gear is sleeved on the roller shaft of each first conveying roller 221 to mesh with the chain. The gear of one of the first transmission assemblies 222 is connected to the output shaft of the first drive assembly 223. The first drive assembly 223 can be a servo geared motor, which is fixed above the first frame 211 by a connecting frame.

[0056] It should be noted that the first transmission component 222 mentioned above can also be replaced by a transmission structure with a pulley and a belt.

[0057] In addition, among the multiple first conveying rollers 221, there are multiple double-end drive head rollers 224 and one single-end drive roller 225, with the single-end drive roller 225 located on the side of the multiple double-end drive head rollers 224.

[0058] Specifically, the single-end drive roller 225 refers to a single, continuous roller connected to the first frame 211 via a shaft; the double-end drive roller 224 refers to two rollers simultaneously mounted on a shaft via bearings, with a certain gap between them. This gap is longer than the width of the second pressure plate 422, ensuring that the movement of the second pressure plate 422 is not interfered with, and also preventing interference with the telescopic rod and guide rod 440 of the telescopic drive device 410. The ends of the two rollers in the double-end drive roller 224 are connected to gears, thus enabling individual driving of the two rollers. The single-end drive roller 225 is used to achieve the linkage between the two rollers in the double-end drive roller 224.

[0059] As a preferred embodiment, the second conveyor roller assembly 230 can be a roller mill; specifically, the second conveyor roller assembly 230 includes multiple second conveyor rollers 231, a second transmission assembly 232, and a second drive assembly 233. The multiple second conveyor rollers 231 are rotatably connected to the second frame 212 respectively; the multiple second conveyor rollers 231 are connected to each other through the second transmission assembly 232. The second transmission assembly 232 can be in the form of a gear and a toothed belt, that is, a gear is sleeved on the roller shaft of each second conveyor roller. The gear of one of the second transmission assemblies 232 is connected to the output shaft of the second drive assembly 233. The second drive assembly 233 can be a servo geared motor, which is fixed to the bottom of the second frame 212 through a connecting bracket.

[0060] It should be noted that the second transmission component 232 mentioned above can also be replaced by a transmission structure with a pulley and belt.

[0061] The automatic tire-turning device provided in this embodiment has at least the following advantages:

[0062] 1. The supporting conveyor device 200 adopts a frame form, which is simple and stable in structure;

[0063] 2. The tire is rolled over by pressing down the tire with a 400mm tire-pressing device, and the control structure is simple;

[0064] 3. The cylinder uses a pressure regulating valve to adjust the pressure according to different tire specifications, pressing down tires of different weights, so that the tires are not easily deformed.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
