Description

Technical Field

[0001] This application belongs to the technical field of tire appearance inspection equipment, and specifically relates to a tire barcode scanning auxiliary system. Background Technology

[0002] Before tire appearance inspection, the tires need to be scanned to obtain necessary tire information. To improve the efficiency of tire scanning, in the existing technology, a scanning device with a shooting function is set above a conveyor that can automatically transport tires. Tires are put on the conveyor by manual labor or feeding equipment at the feeding end of the conveyor. The tires are placed flat on the conveyor and transported to the scanning station of the scanning device in sequence. The scanning device shoots and recognizes the information code on the upper sidewall surface of the tire, thereby realizing the automatic acquisition of tire information.

[0003] However, tires typically only have an information code on one sidewall. Due to oversight, it's difficult to ensure that all sidewalls with information codes are identified as upper sidewalls by the scanning device when tires are placed on the conveyor. Therefore, there is a risk of missed scanning when the information code is on the lower sidewall. If a missed scan occurs, the tire still needs to be manually flipped, wasting manpower and reducing scanning efficiency. Utility Model Content

[0011] Preferably, the barcode scanning auxiliary system further includes a lifting device, which includes a second driving member and a lifting platform. The first base has a accommodating gap hollowed out between the moving tracks of the driving rollers. The second driving member is disposed within the accommodating gap. The lifting platform includes a mounting plate and at least two tire support rollers. The mounting plate is horizontally disposed at the output end of the second driving member. The two tire support rollers are fixed to the top of the mounting plate.

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The technical solutions of this application will be further described below with reference to the accompanying drawings of the embodiments, and this application is not limited to the following specific implementation methods.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limitations on this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The present application will be further described in detail with reference to specific embodiments.

[0028] This application discloses a tire barcode scanning auxiliary system (hereinafter referred to as the "barcode scanning auxiliary system"). The system includes a conveying device 20, a first barcode scanning device 10, and a second barcode scanning device 11. The conveying device 20 can be a roller conveyor or a belt conveyor for conveying tires. The conveying device 20 has a barcode scanning gap 21 along the tire conveying direction, which exposes the underside of the tire. The first barcode scanning device 10 and the second barcode scanning device 11 can be cameras capable of capturing tire information codes. See attached diagram. Figure 1 The first scanning device 10 is suspended above the conveyor 20 via a support member located on one side of the conveyor 20. The first scanning device 10 can take downward images, and the area of ​​the conveyor 20 covered by its field of view is considered the first scanning station; see appendix. Figure 2 The second scanning device 11 is disposed within the scanning gap 21 and is capable of upward scanning. The area of ​​the conveying device 20 covered by its scanning field of view is regarded as the second scanning station. In one embodiment, the first scanning station and the second scanning station can be located at two positions in the tire conveying direction, respectively; in another embodiment, the first scanning station and the second scanning station can also be located at the same position, that is, the first scanning device 10 and the second scanning device 11 are aligned.

[0029] Using the above-mentioned barcode scanning assistance system has at least the following beneficial effects: The conveying device 20 conveys tires to the area below the first scanning device 10 and above the scanning gap 21. For tires with information codes located on the upper outer tire side, the first scanning device 10 can scan the information codes downwards; for tires with information codes located on the lower outer tire side, the second scanning device 11 can scan the information codes upwards. This allows the tires to be identified in a single conveying process, reducing the risk of missed scanning of tire information codes. Compared to existing technologies, there is no need to flip the tires when the information codes are not identified, thus improving the tire scanning efficiency.

[0030] Based on the above embodiments, this application also provides some specific implementation methods to improve the above solutions.

[0031] When the information code is on the outer sidewall of the tire, the selection of the conveying device 20 does not affect the scanning effect of the first scanning device 10 on the tire; however, when the information code is on the underside of the tire, the scanning gap 21 on the conveying device 20 needs to remain in place and not move with the tire's position, so that the second scanning device 11 can scan at a fixed position. To achieve this effect, the conveying device 20 includes a left conveying roller group 22 and a right conveying roller group 23. The left conveying roller group 22 and the right conveying roller group 23 are on the same horizontal plane to form a roller track that can directionally convey the tire. A scanning gap 21 parallel to the tire conveying direction is formed between the left conveying roller group 22 and the right conveying roller group 23.

[0032] The aforementioned left conveyor roller group 22 and right conveyor roller group 23 are each composed of several parallel conveyor rollers 24. The left conveyor roller group 22 and right conveyor roller group 23 move synchronously to directionally convey the tire. Specifically, the conveying device 20 also includes a roller frame 25, which forms an installation gap along the tire conveying direction. The several conveyor rollers 24 that make up the left conveyor roller group 22 and right conveyor roller group 23 are arranged between the roller frame 25. When the tire is conveyed in the center by the roller conveyor composed of the left conveyor roller group 22 and right conveyor roller group 23, the information code on the lower outer tire side can be exposed to the second scanning device 11 when the tire reaches above the scanning gap 21.

[0033] Furthermore, due to the limited width of the scanning gap 21, the exposed area of ​​the tire's lower outer sidewall is also limited. Even adjusting the height of the second scanning device 11 has a very limited effect on the change in the field of view. For small-sized tires, the area of ​​the lower outer sidewall exposed by the scanning gap 21 is sufficient for the second scanning device 11 to acquire the complete information code with just one shot; however, for larger-sized tires, the position and area of ​​the information code are relatively larger, and the scanning gap 21 can only partially expose the information code. To facilitate the second scanning device 11 in acquiring the complete information code, the scanning auxiliary system also includes a rotating device 30, which can drive the tire to rotate above the scanning gap 21, ensuring that the information code is fully exposed during rotation, allowing the second scanning device 11 to acquire the complete information code through multiple shots.

[0034] Specifically, see Appendix Figure 3 The aforementioned rotating device 30 includes a first base 34, a driving mechanism 33, and four driving rollers. The first base 34 is positioned below the conveying roller 24 relative to the first scanning device 10 and / or the second scanning device 11. Four drive rollers are perpendicular to the conveyor rollers 24. Two drive rollers are positioned between a pair of adjacent conveyor rollers 24, and the other two drive rollers are positioned between another pair of adjacent conveyor rollers 24. Each drive roller is slidably connected to the top of the first base 34, thereby forming a tire clamping gap between the four drive rollers above the conveyor rollers 24. The four drive rollers are distributed on both sides of the scanning gap 21. The drive mechanism 33 is driven by at least one drive roller. The drive mechanism 33 is used to drive the drive rollers to center and clamp the tire above the scanning gap 21, so that at least a portion of the lower outer tire side of the tire is confined to the center of the scanning gap 21. In one embodiment, the drive rollers include at least one active roller 31. When the tire is clamped by the drive rollers, the active roller 31 can actively rotate around its axis, driving the tire to rotate, so that the second scanning device 11 and the first scanning device 10 can obtain complete information codes by taking multiple photos during the tire rotation.

[0035] In one embodiment, the aforementioned driving rollers also include a driven roller 32. When the tire is clamped, the driven roller 32 only serves to limit the clamping of the tire and guide the tire to rotate around its own axis, without actively driving the tire to rotate. Compared to the embodiment where all driving rollers are driving rollers 31, the driven roller 32 does not need to be equipped with a drive motor like the driving roller 31, nor does it need to have its rotation speed uniformly controlled.

[0036] Specifically, the drive roller 31 is an automatic roller with a built-in drive motor, which can rotate automatically at a set speed; the driven roller 32 is an ordinary roller that only rotates when subjected to tangential force on the outside. When the drive roller 31 and the driven roller 32 approach and contact the tire and stop moving, the maximum distance between the drive roller 31 and the driven roller 32 should be less than the tread diameter of the tire to be tested, so that the tire is restricted by the drive roller 31 and the driven roller 32 around it and can only rotate around the axis under the driving action of the drive roller 31.

[0037] To ensure precise tire clamping action by each drive roller, the top of the first base 34 is provided with at least one first guide rail 341 and at least one second guide rail 342 parallel to the conveying roller 24. In one embodiment, one pair of drive rollers can slide along the first guide rail 341, and the other pair can slide along the second guide rail 342. Specifically, the lower end of each drive roller is provided with a sliding seat 343. One pair of sliding seats 343 is slidably disposed on the first guide rail 341, and another pair of sliding seats 343 is slidably disposed on the second guide rail 342. The sliding seats 343 can slide along the first guide rail 341 and the second guide rail 342 respectively. The drive mechanism 33 includes at least one first drive member 331, which is selected from one of the drive devices capable of outputting power in a straight line, such as a drive cylinder, an electric telescopic cylinder, or an electric push rod. The first driving member 331 is disposed on one side of the first base 34. At least one sliding seat 343 at the lower end of the driving roller is connected to the output end of the first driving member 331 in a transmission engagement. The first driving member 331 can drive the sliding seats 343 on the first guide rail 341 and the second guide rail 342 to converge towards the central axis of the roller conveyor, so that the four driving rollers center and clamp the tire. In the above embodiment, the number of first driving members 331 can be one, two, or four. When there are one or two first driving members 331, the first driving member 331 needs to achieve synchronous transmission engagement with the four driving rollers through a transmission mechanism to achieve synchronous movement of the driving rollers. For example, at least two of the four sliding seats 343 can be connected as one unit and connected to at least one first driving member 331. When there are four first driving members 331, the four first driving members 331 can drive each driving roller to move towards the tire centering position.

[0038] During the tire centering and clamping process, four drive rollers need to move synchronously towards the axis of symmetry parallel to the tire conveying direction and located within the tire clamping gap to ensure precise tire centering. However, the more numerous the first drive members 331, the more complex the transmission mechanism or the more precise the control system is required to control the synchronous movement of each first drive member 331. To simplify the structure of the rotating device 30, in one embodiment, see Appendix Figure 5The aforementioned second guide rail 342 consists of two rails, each with a length not exceeding half the length of the first guide rail 341. The two second guide rails 342 are spaced apart on one side of the first guide rail 341 and symmetrically distributed relative to the tire's transport direction. In this embodiment, the aforementioned first base 34 includes three spaced base plates, two of which are shorter and symmetrically distributed relative to the tire's transport direction. The longer base plate is parallel to the shorter base plate. The two second guide rails 342 are respectively disposed on the top of the two shorter base plates, and the first guide rail 341 is disposed on the top of the longer base plate. The first guide rail 341 is disposed in one of the four sliding seats 343 located at the lower end of the four drive rollers. One pair of sliding seats 343 is slidably connected to two of the second guide rails 342, and the other pair is slidably connected to the first guide rail 341.

[0039] In addition, the aforementioned drive mechanism 33 also includes a transmission belt 332, at least four first guide pulleys 333, at least four second guide pulleys 334, and two third guide pulleys 335. Preferably, in this embodiment, there are four first guide pulleys 333 and four second guide pulleys 334. The two third guide pulleys 335 are located at opposite ends of the two second guide rails 342 and are rotatably connected to the first base 34. The two first guide pulleys 333 are located at both ends of the first guide rails 341 and are rotatably connected to the first base 34. The other two first guide pulleys 333 are distributed at opposite ends of the two second guide rails 342 and are rotatably connected to the first base 34. The four second guide pulleys 334 are symmetrically distributed between opposite sides of the first guide rails 341 and the second guide rails 342 and are rotatably connected to the first base 34. The rectangle formed by the lines connecting the four second guide pulleys 334 is located within the rectangle formed by the lines connecting the four first guide pulleys 333. The transmission belt 332 is loop-shaped. Both ends of the transmission belt 332 are respectively sleeved with the third guide pulley 335, and the side of the first guide pulley 333 is in frictional contact with the inner surface of the transmission belt 332; the side of the second guide pulley 334 is in frictional contact with the outer surface of the transmission belt 332, so that the transmission belt 332 is subjected to tension at the first guide pulley 333, the second guide pulley 334 and the third guide pulley 335.

[0040] Furthermore, the two opposing sides of a pair of sliding seats 343 on the first guide rail 341 are respectively fixedly connected to the transmission belt 332; the opposing sides of another pair of sliding seats 343 on the second guide rail 342 are respectively fixedly connected to the transmission belt 332; the output end of the first driving member 331 is fixedly connected to any one of the sliding seats 343. In this embodiment, see the attached diagram. Figure 4 and appendix Figure 5On the first guide rail 341, a limiting clip 344 is fixed to the lower side of the left sliding seat 343. The limiting clip 344 can clamp the portion of the transmission belt 332 near the lower side of the first guide rail 341. On the upper side of the right sliding seat 343, the limiting clip 344 can clamp the portion of the transmission belt 332 near the upper side of the first guide rail 341. In addition, on the second guide rail 342, a limiting clip 344 is fixed to the lower side of the left sliding seat 343. The limiting clip 344 can clamp the portion of the transmission belt 332 near the lower side of the second guide rail 342. On the upper side of the right sliding seat 343, the limiting clip 344 can clamp the portion of the transmission belt 332 near the upper side of the second guide rail 342, thereby fixing the transmission belt 332 to each sliding seat 343. The first driving member 331 is parallel to the first guide rail 341 and is distributed on the side of the first guide rail 341 away from the second guide rail 342. One end of the output shaft of the first driving member 331 is fixedly connected to the sliding seat 343 on the left side of the first guide rail 341 through the connecting rod 336.

[0041] When using the rotating device 30 of this embodiment, the initial position of the sliding seat 343 is located at both ends of the first guide rail 341 and the end of the second guide rail 342 that is separate from it. The initial state of the output shaft of the first driving member 331 is the extended state. When the output shaft of the first drive member 331 retracts, it drives the sliding seat 343 on the left side of the first guide rail 341 to move to the right. The sliding seat 343 causes the portion of the transmission belt 332 near the lower side of the first guide rail 341 to move to the right. Under the guidance of the first guide wheel 333, the portion of the transmission belt 332 near the upper side of the first guide rail 341 moves to the left, causing the sliding seat 343 on the right side of the first guide rail 341 to move to the left. At the same time, the portion of the transmission belt 332 near the lower side of the second guide rail 342 moves to the right under the guidance of the third guide wheel 335, causing the sliding seat 343 on the left side of the second guide rail 342 to move to the right. Similarly, the portion of the transmission belt 332 near the upper side of the right side of the second guide rail 342 moves to the left under the guidance of the third guide wheel 335 and the second guide wheel 334, causing the sliding seat 343 on the right side of the second guide rail 342 to move to the left. This causes the two drive rollers on the left and the two drive rollers on the right of the roller conveyor axis to converge synchronously towards the central axis of the roller conveyor, thereby centering and clamping the tire.

[0042] However, since the conveying rollers 24 of the conveying device 20 are all distributed along the tire conveying direction, the rolling surface of the conveying rollers 24 will increase the resistance on the lower sidewall of the tire for the rotating tire, which will cause the tire to be unstable during rotation.

[0043] Therefore, a lifting device 40 is needed to lift the tire off the conveyor roller 24, allowing the lower tire sidewall to disengage from the conveyor roller 24 before rotation. In one embodiment, see attached drawing. Figure 6 The system also includes a lifting device 40, which comprises a second drive member 41 and a lifting platform 42. In this embodiment, to enable the lifting device 40 to cooperate with the rotating device 30 to lift the tire located between the four drive rollers upward, the first base 34 is provided with a accommodating gap 345. The accommodating gap 345 is located between the first guide rail 341 and the second guide rail 342. The second drive member 41 is disposed within the accommodating gap 345. The lifting platform 42 includes a mounting plate 421 and at least two tire support rollers 422. Specifically, the second drive member 41 is also selected from one of the drive devices that can output power in a straight line, such as a drive cylinder, an electric telescopic cylinder, or an electric push rod. The output end of the second drive member 41 can pass through the accommodating gap 345 in a vertical direction to lift the mounting plate 421.

[0044] Two tire support rollers 422 are fixed to the top of the mounting plate 421, and their rolling surfaces can form a plane supporting the lower tire sidewall, and the tire support rollers 422 can rotate along their axes. For details, see the appendix. Figure 7 To reduce the area of ​​the mounting plate 421 and ensure that the lower tire sidewall is fully exposed to the second scanning device 11, several support arms 425 are horizontally arranged on the top of the mounting plate 421. One end of each support arm 425 extends from the edge of the mounting plate 421, and the gaps between the support arms 425 are used by the second scanning device 11 to obtain the information code of the lower tire sidewall. The two ends of the tire support roller 422 are fixed to the top of the support arm 425 by vertically arranged brackets 424. The sides of adjacent tire support rollers 422 can form a plane for horizontal tire support; and the tire support roller 422 is rotatably connected to the bracket 424, so that it can rotate around its axis with the tire when the tire rotates.

[0045] Specifically, a first lifting channel 26 parallel to the tire conveying direction is formed between the left conveying roller group 22 and the right conveying roller group 23. The first lifting channel 26 is located on one side of the scanning gap 21 and is connected to the scanning gap 21. At least one tire support roller 422 of the tire lifting device 40 is parallel to the tire conveying direction and is disposed in the first lifting channel 26. In the left conveying roller group 22 or the right conveying roller group 23, a second lifting channel 27 is formed between at least two adjacent conveying rollers 24. At least one tire support roller 422 is parallel to the conveying roller 24 and is disposed in the second lifting channel 27. In this way, the rolling surfaces of at least two tire support rollers 422 can form a plane supporting the lower tire sidewall.

[0046] Once the tire reaches the clamping gap, the drive roller first centers the tire, and then the second drive member 41 drives the tire support roller 422 upward. The lifting platform 42, composed of the tire support roller 422, is lifted above the conveyor roller 24, causing the lower tire side to disengage from the conveyor roller 24. In this state, the drive roller 31 drives the tire to rotate. The tire support roller 422 can stably support the tire and rotate with it, reducing the probability of tire instability. It should be noted that the lifting height of the tire support roller 422 is less than the rolling surface length of the drive roller, ensuring that the drive roller can still clamp the tire when it is lifted to its highest position.

[0047] Furthermore, to ensure the system for lifting the tire can stably lift it and reduce the axial friction between the tire and the tire support rollers 422, the lifting platform 42 includes five tire support rollers 422. Three of these tire support rollers are parallel to the tire's conveying direction and arranged in a triangular pattern within the first lifting channel 26. One pair of these three tire support rollers is symmetrically distributed on both sides of the second scanning device 11. The remaining two tire support rollers 422 are parallel to the conveying rollers 24 and are arranged in the second lifting channel 27, symmetrically distributed on both sides of the first lifting channel 26. This not only improves the stability of tire support but also, the more dispersed arrangement of the five tire support rollers 422 relative to the two conveying rollers 24 helps reduce the axial friction on the tire support rollers 422 during tire rotation, making the tire rotation process more stable. In addition, since the tire support rollers 422 are distributed sufficiently, they do not cause too much interference to the scanning field of view of the second scanning device 11, so that the information code on the underside of the tire can still be fully exposed to the second scanning device 11 under the rotation of the rotating device 30.

[0048] Furthermore, the output end of the second drive member 41 is provided with a floating joint 423. The end of the floating joint 423 away from the second drive member 41 is connected to the bottom of the mounting plate 421. During the process of the second drive member 41 driving the mounting plate 421 to move in the vertical direction, the floating joint 423 can not only compensate for the assembly error between the mounting plate 421 and the second drive member 41 in the guiding direction and reduce the deviation angle of the output shaft of the second drive member 41 from the Z-axis during the lifting process, but also absorb the vibration and impact generated by the change of center of gravity of the tire during rotation. This ensures that the second drive member 41 only bears the force in the Z-axis direction during the lifting process, and extends the service life of the electric telescopic cylinder or drive cylinder that serves as the second drive member 41.

[0049] Furthermore, to ensure that the lifting platform 42 remains level throughout the lifting process, see Appendix Figure 6 To be continued Figure 8The lifting device 40 also includes a second base 43 and several linear guide mechanisms 44. The second base 43 is located below the first base 34 with a relative accommodating gap 345. The second driving member 41 is perpendicular to the second base 43 and its lower end is fixed to the second base 43. Several linear guide mechanisms 44 are evenly distributed around the second driving member 41 and their two ends are respectively connected to the second base 43 and the mounting plate 421. They can guide the mounting plate 421 to move in a straight line in the vertical direction relative to the second base 43, thereby dispersing the interference of tire gravity on the horizontal state of the lifting platform 42 and the driving direction of the second driving member 41.

[0050] Specifically, the linear guide mechanism 44 includes a guide post 441 and a linear bearing 442. The guide post 441 is perpendicular to the second base 43, and its lower end is fixedly connected to the horizontal plane of the second base 43 through a flange. The linear bearing 442 is sleeved on the side of the guide post 441 and slides with the guide post 441. The upper end of the linear bearing 442 is fixedly connected to the bottom of the mounting plate 421 through a flange. In order to allow the guide post 441 to slide relative to the linear bearing 442, the mounting plate 421 and the flange are provided with guide holes relative to the linear bearing 442. Under the restriction of the linear bearing 442, the mounting plate 421 can only move vertically upward along the guide post 441 under the thrust of the second drive member 41 along the Z-axis. When the second drive member 41 is unloaded and the output shaft moves downward, the mounting plate 421 can move vertically downward along the guide post 441, so that the connection between the output shaft and the mounting plate 421 is not subject to the force deviating from the Z-axis, further enhancing the protection of the second drive member 41.

[0051] Based on the above tire scanning assistance system, the following effects can be achieved: the conveying device 20 accurately conveys the tire between the drive rollers of the rotating device 30. The drive rollers first clamp and center the tire, exposing the lower outer tire sidewall to the scanning gap 21. If the scanning device 10 cannot obtain the complete information code at the same position due to different tire sizes, the lifting device 40 can first lift the tire away from the conveying roller 24, and then the active roller 31 drives the tire to rotate, so that the information code is fully displayed to the first scanning device 10 or the second scanning device 11 during the rotation process. This ensures that the scanning assistance system can scan tires of various sizes and avoids the problem of missing information codes.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
