Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a tire blank centering-rotation positioning-code reading device. Background Technology

[0002] Tire production involves many processes, such as raw material processing, batching, mixing, component preparation, tire blank forming, vulcanization, and quality inspection. Furthermore, the tire blank must be rotated to a specific position before vulcanization to ensure it enters the vulcanizing machine and protect the traceability barcode on the blank. Different sizes of tire blanks require different rotation angles, thus precise positioning is crucial. Current methods typically use electric rollers to lift and rotate the tire blank, but this method is inaccurate and has significant errors. Another common method involves keeping the connecting wires stationary while using a cylinder and guide rod at the top to lift the tire blank and then rotate it as a whole. This mechanism increases the structural height, affecting the arrangement of the second-layer production line, and is also cumbersome. Utility Model Content

Detailed Implementation

[0042] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0043] Please see Figures 1-3 , Figure 7 , Figure 8This application discloses a "centering-rotational positioning-code reading" device for tire blanks, including a frame 1, a lifting mechanism 2, a horizontal conveying mechanism 3, a centering mechanism 4, a rotational positioning mechanism 5, and a code reading mechanism 6. The lifting mechanism 2 is disposed on the frame 1. The horizontal conveying mechanism 3 is connected to the lifting mechanism 2. The centering mechanism 4 is mounted on the horizontal conveying mechanism 3 and includes a centering drive member 41, a first centering component 42 and a second centering component 43 disposed opposite to each other.

The code reading mechanism 6 is disposed on the frame 1 and located on one side of the rotational positioning mechanism 5.

[0044] Please see Figures 4-6 The lifting mechanism 2 includes a lifting motor assembly 21, a sprocket assembly 22 and two lifting chains 23 connected to each other. The lifting motor assembly 21 is used to drive the sprocket assembly 22 to rotate, and the sprocket assembly 22 is used to drive the two lifting chains 23 to move.

[0045] Please see Figure 7 The horizontal conveying mechanism 3 includes a conveying frame 31 and a conveying drive assembly 32, an omnidirectional ball assembly 33, and two conveying roller assemblies 34 mounted on the conveying frame 31. The omnidirectional ball assembly 33 is located between the two conveying roller assemblies 34. The conveying drive assembly 32 is connected to the omnidirectional ball assembly 33 and the two conveying roller assemblies 34 respectively to drive the omnidirectional ball assembly 33 and the two conveying roller assemblies 34 to rotate. This reduces the friction between the omnidirectional ball assembly and the tire blank during the horizontal conveying process, facilitating the clamping and centering of the tire blank by the subsequent centering mechanism 4. Two lifting chains 23 are connected to both sides of the conveying frame 31. The two free ends of each lifting chain 23 are fixedly connected to the conveying frame 31. The two free ends of each lifting chain 23 can rise or fall vertically, thereby driving the horizontal conveying mechanism 3 to rise and fall through the two lifting chains 23.

[0046] Please see Figure 8 The centering drive component 41 includes a cylinder 411, a first linkage component 412, a linkage rod 413, and a second linkage component 414. One end of the first linkage component 412 is hinged to the output rod of the cylinder 411, and the other end is hinged to one end of the linkage rod 413. The other end of the linkage rod 413 is hinged to the second linkage component 414.

[0047] Each first clamping arm 421 is connected to a first vertical shaft 422, and a first gear 423 is fixed on each first vertical shaft 422. Two first gears 423 mesh with each other. One of the first vertical shafts 422 extends downward and is connected to a first linkage member 412. Each second clamping arm 431 is connected to a second vertical shaft 432, and a second gear 433 is fixed on each second vertical shaft 432. Two second gears 433 mesh with each other. One of the second vertical shafts 432 extends downward and is connected to a second linkage member 414.

[0048] The first linkage 412 includes a first sleeve 4121 and two first linkage seats 4122 connected to the outer peripheral wall of the first sleeve 4121. The extension end of the first vertical shaft 422 is connected to the first sleeve 4121. The output rod of the cylinder 411 is hinged to one of the first linkage seats 4122, and the other first linkage seat 4122 is hinged to one end of the linkage rod 413. The second linkage 414 includes a second sleeve 4141 and a second linkage seat 4142 connected to the outer peripheral wall of the second sleeve 4141. The extension end of the second vertical shaft 432 is connected to the second sleeve 4141, and the other end of the linkage rod 413 is hinged to the second linkage seat 4142.

[0049] To facilitate smooth movement of the two first clamping arms 421 and the two second clamping arms 431 towards or away from each other, the first centering assembly 42 preferably further includes a first centering frame 424, on which two first bearings 425 are mounted. Each first vertical shaft 422 is connected to and passes through the corresponding first bearing 425. The second centering assembly 43 further includes a second centering frame 434, on which two second bearings 435 are mounted. Each second vertical shaft 432 is connected to and passes through the corresponding second bearing 435. Both the first centering frame 424 and the second centering frame 434 are fixed to the conveyor frame 31.

[0050] Preferably, each first clamping arm 421 has multiple first rollers 426 arranged in parallel on one side for clamping, and each second clamping arm 431 has multiple second rollers 436 arranged in parallel on one side for clamping, to ensure that the tire blank can rotate freely during the clamping process.

[0051] Please see Figures 9-12 The lifting claw mechanism 52 includes a lifting claw drive assembly 521, a lead screw assembly 522 connected to the lifting claw drive assembly 521, and multiple linkage lifting claw assemblies 523 connected to the lead screw assembly 522. Each linkage lifting claw assembly 523 includes a link assembly 5231 and a lifting claw 5232 connected to the link assembly 5231. The lifting claw drive assembly 521 drives the lead screw assembly 522 to move in the vertical direction, thereby driving the link assembly 5231 to move, realizing the lifting claw 5232 to lift the tire blank.

[0052] Specifically, the lead screw assembly 522 is connected to the support plate 524, and the connecting rod assembly 5231 includes a first connecting rod 5233 and a second connecting rod 5234. One end of the first connecting rod 5233 is hinged to the support plate 524, and the other end is hinged to the middle of the second connecting rod 5234. One end of the second connecting rod 5234 is hinged to the rotating frame 51, and the other end is connected to the lifting claw 5232. The lead screw assembly 522 includes a lead screw 5221 and a lead screw nut 5222 that cooperates with the lead screw 5221. When the claw drive assembly 521 is activated, the lead screw 5221 of the drive screw assembly 522 rotates, causing the lead screw nut 5222, which cooperates with the lead screw 5221, to move vertically. The support plate 524 is fixedly connected to the lead screw nut 5222. The lead screw nut 5222 drives the support plate 524 to move vertically, thereby driving the first connecting rod 5233 to move. The first connecting rod 5233 drives the second connecting rod 5234 to move, and the second connecting rod drives the claw 5232 to move to open or close.

[0053] In this embodiment, the claw drive assembly 521 includes a claw motor assembly 5211, a first synchronous pulley 5212, a second synchronous pulley 5213, and a first synchronous belt 5214. The first synchronous pulley 5212 is connected to the claw motor assembly 5211, and the first synchronous belt 5214 connects the first synchronous pulley 5213 and the second synchronous pulley 5214. The rotary drive assembly 53 includes a rotary motor assembly 531, a third synchronous pulley 532, a fourth synchronous pulley 533, and a second synchronous belt 534. The third synchronous pulley 532 is connected to the rotary motor assembly 531, and the second synchronous belt 534 connects the third synchronous pulley 532 and the fourth synchronous pulley 533. The second synchronous pulley 5214 is connected to the lead screw 5221 of the lead screw assembly 522. The lead screw 5221 is rotatably connected to the rotating frame 51, and the fourth synchronous pulley 533 is fixedly connected to the rotating frame 51.

[0054] To improve the compactness of the structure while avoiding increasing the height of the structure, it is preferable that the claw motor assembly 5211 and the rotary motor assembly 531 are located on both sides of the rotating frame 51 and are arranged opposite to each other, and the second synchronous pulley 5213 is located above the fourth synchronous pulley 533.

[0055] The preferred rotating frame 51 includes a rotating frame body 511, a support sleeve 512 connected to the rotating frame body 511, and a rotating body 513 connected to the support sleeve 512. A first tapered roller bearing 514 is provided inside the support sleeve 512. The upper part of the lead screw 5221 is connected to the second synchronous pulley 5213 and cooperates with the first tapered roller bearing 514. The inner ring of the rotating body 513 can rotate, and the outer ring of the rotating body 513 is fixed to the frame 1. The fourth synchronous pulley 533 is fixedly connected to the rotating frame body 511.

[0056] In order to facilitate the uniform distribution of the structure on the rotating frame 51 and to facilitate the stable rotation of the rotating frame 51, the rotating frame 511 is preferably in the shape of a disc.

[0057] To improve the linearity of the vertical movement of the support plate 524, it is preferable that the lower part of the rotating frame 511 is provided with multiple guide shafts 515, and the support plate 524 is provided with multiple linear bearings 516, with each guide shaft 515 passing through a corresponding linear bearing 516. When the support plate 524 is driven, it moves linearly along the guide shafts 515 through the linear bearings 516, thereby achieving the accuracy of the linear movement of the support plate 524 and driving the lifting claw 5232 to move through the connecting rod assembly 5231.

[0058] The lower part of the rotating frame 511 is provided with multiple first buffer pads 517. The lower part of the lead screw 5221 is rotatably connected to the base plate 518. The base plate 518 is provided with multiple second buffer pads 519. The upper and lower parts of the guide shaft 515 extend into the first buffer pads 517 and the second buffer pads 519, respectively. The first buffer pads 517 and the second buffer pads 519 facilitate the buffering of the up-and-down movement of the support plate 524. The first buffer pads 517 and the second buffer pads 519 can be made of polyurethane. Specifically, the base plate 518 is provided with a second tapered roller bearing 5181, and the lower part of the lead screw 5221 is connected to the second tapered roller bearing 5181.

[0059] To facilitate the installation of the claw drive assembly 521 and the rotary drive assembly 53, preferably, the first fixing part 52111 of the claw motor assembly 5211 is connected to the first support seat 52112, and the second fixing part 5311 of the rotary motor assembly 531 is connected to the second support seat 53112. Both the first support seat 51112 and the second support seat 53112 are fixed to the frame 1.

[0060] Please see Figure 13 The barcode reading mechanism 6 includes a barcode reading profile 61, two profile supports 62 mounted at both ends of the barcode reading profile 61, two adjusting supports 63 mounted on both sides of the barcode reading profile 62, a camera support 64 connecting the two adjusting supports 63, and a camera 65 connected to the camera support 64. The barcode reading mechanism 6 is fixed to the frame by the two profile supports 62. The adjusting supports 63 have elongated holes 631 that extend vertically, allowing the adjusting supports 63 to move along the length of the barcode reading profile 61. The camera support 64 has arc-shaped holes 641, allowing the camera 65 to be adjusted horizontally and vertically, and also allowing the camera 65 to be adjusted in angle, thus improving the accuracy of barcode reading.

[0061] Please see Figure 4 , Figure 5The frame 1 is equipped with a stop switch 11, an upper limit switch 12, a lower limit switch 13, an upper anti-collision block 14, and a lower anti-collision block 15. The stop switch 11 is used to stop the lifting mechanism 2 when it drives the horizontal conveyor mechanism to lift to the designated position. The upper limit switch 12 and the lower limit switch 13 are used to limit the upper and lower limits of the lifting mechanism 2 and then cut off the power to prevent overtravel. The upper anti-collision block 14 and the lower anti-collision block 15 are used to buffer overtravel and ensure safety.

[0062] In use, the horizontal conveying mechanism 3 connects to the incoming material conveying line. The conveying roller assembly 34 and the omnidirectional ball assembly 33 rotate, driving the tire blank to move. The lifting motor assembly 21 drives the sprocket assembly 22, which in turn drives two lifting chains 23 to lift the horizontal conveying mechanism 3 and the centering mechanism 2 to the corresponding positions. The cylinder 411, through the first linkage 412, the linkage rod 413, and the second linkage 414, drives the two first clamping swing arms 421 of the first centering assembly 42 and the two second clamping swing arms 431 of the second centering assembly 43, causing the two first clamping swing arms 421 and the two second clamping swing arms 431 to simultaneously clamp the tire blank towards the center, so that the tire blank is in the center position. The lifting mechanism 2 lifts the centering mechanism 4 to the lifting claw position. At this time, the lifting... The claw drive assembly 521 drives the lead screw assembly 522, which in turn drives the connecting rod assembly 5231 to open the claw 5232. The claw 5232 hooks the tire carcass, and the lifting mechanism drives the centering mechanism to descend, so that the tire carcass is disengaged from the horizontal conveying mechanism. Then, the rotation drive assembly 53 drives the rotating frame 51 to rotate the tire carcass. When it reaches the corresponding position, if the barcode reading mechanism 6 can scan the traceability barcode on the tire carcass through the camera 65, the rotation positioning mechanism 5 stops the tire carcass from rotating. The barcode information is entered into the barcode reading mechanism 6, and the lifting mechanism 2 lifts the centering mechanism 4 to the claw picking position again. The claw 5232 retracts, and the centering mechanism 4 falls onto the lifting mechanism 2. The lifting mechanism 2 drives the centering mechanism 4 to descend to the conveying docking position, and the tire carcass is sent out. The operation is completed.
