Description

Technical Field

[0001] The present invention relates to the technical field of equipment for tire inspection, and particularly to a tire transfer device and a tire appearance inspection production line. Background Art

[0002] After tire vulcanization, it is necessary to inspect the tread and the sidewalls on both sides of the tire. The conventional method is to manually turn the tire for inspection. However, due to the large size and weight of the tire, the manual turning of the tire consumes a large amount of physical strength of the operator, and the inspection efficiency is low. Therefore, in the prior art, the tire is mostly fixed vertically on the inspection table to inspect the tread and the sidewalls on both sides of the tire. However, this method requires the vertically placed tire to be transported to the inspection table in a freely rolling manner. Since the tire has a certain elasticity, when the tire contacts the tire blocking roller on the inspection table in a rolling manner, the tire will bounce, which may cause pinching and squeezing injuries to the operator. Moreover, long-term impact on the tire blocking roller will also have a certain impact on the service life of the tire blocking roller.

[0003] Therefore, designing a tire transfer device and an appearance inspection production line to improve the safety during tire transfer is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners

[0039] As Figures 1 to 4 shown, the present invention provides a tire transfer device, including an inspection table 1 and an inclined loading table 2; the loading table 2 is communicated with a conveying channel for transporting tires to be inspected. The conveying channel can be located on the side of the loading table 2 and flush with the side surface of the loading table 2, or the conveying channel is located at the top of the loading table 2. Preferably, the conveying channel is located at the top of the loading table 2, and the tires are placed horizontally on the conveying channel. The inspection table 1 is located on one side at the bottom of the loading table 2. A first avoidance groove 3 is formed on the loading table 2; a first placement groove 4 for fixing the position of the tire is formed on the inspection table 1. A support frame 5 perpendicular to the first placement groove 4 is fixedly provided on the inspection table 1. The support frame 5 has a first bearing surface 6 for supporting the tire. The outer contour of the first avoidance groove 3 is not less than the outer contour of the support frame 5, so that the support frame 5 can be fitted into the first avoidance groove 3; the inspection table 1 is connected to a first driving mechanism for driving the inspection table 1 to rotate. The support frame 5 can rotate from the position fitted in the first avoidance groove 3 to the vertical direction. There is also an inspection station for the operator to inspect the tire in the interval between the first avoidance groove 3 and the vertical direction.

[0040] During operation, the support frame 5 first rotates towards the direction where the first avoidance groove 3 is located under the drive of the first driving mechanism. When the support frame 5 is fitted into the first avoidance groove 3, the first driving mechanism is turned off to make the support frame 5 stay inside the first avoidance groove 3, so that the loading table 2 is communicated with the first placement groove 4, and the tire can slide from the loading table 2 to the first placement groove 4. At this time, the tire is in contact with the first bearing surface 6; then, the first driving mechanism is started to drive the support frame 5 to rotate back towards the vertical direction side and stop the support frame 5 between the vertical direction and the loading table 2, that is, at the inspection station. At this time, the support frame 5 is inclined relative to the vertical direction. The operator can effectively avoid the tire from falling from the inspection table 1 at this station. Compared with the prior art method of rolling the tire onto the inspection table 1 in an upright manner and providing a blocking device on both sides of the tire wall surface to prevent the tire from tipping over, the structure of this application is simple, and it can effectively avoid the problem of pinching or squeezing the operator during the process of the tire rolling onto the inspection table 1, improving the operation safety.

[0041] To reduce the friction force when the tire slides on the loading table 2, preferably, a plurality of roller shafts are provided on the loading table 2. A base 7 is provided at the bottom of the inspection table 1. A rotating shaft 8 is provided on the upper surface of the base 7. The rotating shaft 8 is connected to the side of the inspection table 1 close to the loading table 2 through a connecting plate 9 to reduce the friction force between the inspection table 1 and the base 7 when the inspection table 1 rotates.

[0042] At the top of the carrier table 2, there is an auxiliary support 10 which has a second bearing surface for supporting the tire; the auxiliary support 10 is connected to a second driving mechanism for driving the auxiliary support 10 to rotate. On the carrier table 2, there is a second avoidance groove 11 for fittingly connecting with the auxiliary support 10. The outer contour of the second avoidance groove 11 is not smaller than the outer contour of the auxiliary support 10. The auxiliary support 10 can rotate from the position fitted in the second avoidance groove 11 to the position flush with the transfer channel. On the support frame 5, there is a third avoidance groove 12 for the auxiliary support 10 to pass through the support frame 5. The outer contour of the third avoidance groove 12 is not smaller than the outer contour of the auxiliary support 10.

[0043] During operation, the auxiliary support 10 first rotates to the position flush with the transfer channel, so that the tire is transported from the transfer channel to the auxiliary support 10. Then, the auxiliary support 10 slowly rotates downward until it is fitted in the second avoidance groove 11. At this time, the auxiliary support 10 is flush with the carrier table 2. Since the support frame 5 has been fitted in the first avoidance groove 3 before this, the tire can slide from the auxiliary support 10 to the first placement groove 4 at this time; by setting the auxiliary support 10, the movement speed of the tire from the transfer channel to the first placement groove 4 can be slowed down, so that the tire is transported to the first placement groove 4 in a relatively stable state.

[0044] Among them, the contour of the first avoidance groove 3 is not smaller than the outer contour of the support frame 5, and the contours of the second avoidance groove 11 and the third avoidance groove 12 are not smaller than the outer contour of the auxiliary support 10; the support frame 5 at least includes two support rods 13. The multiple support rods 13 can be parallel to each other or intersect with each other, and the maximum width between adjacent support rods 13 is not greater than the diameter of the tire; the auxiliary support 10 is made of a material that can bear the weight of the tire, and the shape of the auxiliary support 10 can be rectangular, X-shaped, Y-shaped, etc. As a preferred embodiment of the present invention, the support frame 5 includes two support rods 13, and the ends of the two support rods 13 intersect on the inspection table 1 to form a Y-shaped structure; the auxiliary support 10 is a cuboid structure, and the length of the auxiliary support 10 is not less than the diameter of the tire to increase the sliding speed of the tire from the auxiliary support 10. There are also several roller shafts on the auxiliary support 10.

[0045] A first embodiment of the first driving mechanism is a first linear telescopic mechanism 14 inclined on the carrier table 2. There is a first lug 15 on the support frame 5, and the telescopic end of the first linear telescopic mechanism 14 is pivotally connected to the first lug 15. There is a first connecting seat 16 on the carrier table 2, and the fixed end of the first linear telescopic mechanism 14 is pivotally connected to the first connecting seat 16. The telescopic end extends to drive the support frame 5 to rotate in the vertical direction, and the telescopic end shortens to drive the support frame 5 to rotate towards the first avoidance groove 3;

[0046] The second embodiment of the first driving mechanism is a first motor disposed on the inspection table 1, and the rotating shaft of the first motor is fixedly connected to the inspection table 1. By changing the rotation direction of the first motor, the rotation direction of the support frame 5 is changed. The present invention preferably uses the first linear expansion and contraction mechanism 14 as the first driving mechanism.

[0047] The first embodiment of the second driving mechanism is a second linear expansion and contraction mechanism 17 obliquely disposed on the carrying table 2. A second lug 18 is provided on the auxiliary frame 10. The telescopic end of the second linear expansion and contraction mechanism 17 is pivotally connected to the second lug 18. A second connecting seat 19 is provided on the carrying table 2, and the fixed end of the second linear expansion and contraction mechanism 17 is pivotally connected to the second connecting seat 19. When the telescopic end extends, it drives the auxiliary frame 10 to rotate in a direction flush with the conveying channel, and when the telescopic end shortens, it drives the auxiliary frame 10 to rotate in the direction of the second avoidance groove 11.

[0048] The second embodiment of the second driving mechanism is a second motor disposed on the carrying table 2, and the rotating shaft of the second motor is fixedly connected to the auxiliary frame 10. By changing the rotation direction of the second motor, the rotation direction of the auxiliary frame 10 is changed. The present invention preferably uses the second linear expansion and contraction mechanism 17 as the second driving mechanism.

[0049] An active roller 20 and a passive roller 21 are spaced apart on the inspection table 1. The active roller 20 is connected to a third motor 22 for driving the active roller 20 to rotate, and the passive roller 21 is connected to an adjustment assembly for adjusting the height position of the passive roller 21. The active roller 20 and the passive roller 21 form the adjustable first placement groove 4. The adjustment assembly includes a third linear expansion and contraction mechanism 23, a second connecting plate 24, and a support arm 25. Among them, the third linear expansion and contraction mechanism 23 is disposed at the bottom of the inspection table 1. The second connecting plate 24 is a polygonal structure and is respectively rotationally connected to the third linear expansion and contraction mechanism 23 and the inspection table 1. Two support arms 25 are respectively provided on both axial sides of the passive roller 21, and the other ends of the support arms 25 are fixedly connected to the second connecting plate 24. During operation, when the telescopic end of the third linear expansion and contraction mechanism 23 extends, it pulls the passive roller 21 to move downward, and at this time, the tire can roll out of the first placement groove 4. When the telescopic end of the third linear expansion and contraction mechanism 23 shortens, it pulls the passive roller 21 to move upward, and at this time, the tire can be stably fixed in the first placement groove 4.

[0050] Such as Figures 5 to 9As shown in the figure, the present invention also provides a tire appearance inspection production line, which includes two tire transfer devices and a flipping mechanism 26 for adjusting the tire from a vertical position to a horizontal position.

The first tire wall surface 27 faces the operator at the front tire transfer device, and the second tire wall surface 28 faces the operator at the rear tire transfer device. Moreover, the first tire wall surface 27 faces the position where the rear tire transfer device is located, so that the same operator can take into account both the front tire transfer device and the rear tire transfer device at the same time. The tread can be inspected at the front tire transfer device or at the rear tire transfer device.

[0051] The tire appearance inspection production line further includes a first conveying frame 29 for connecting the front tire transfer device and the flipping mechanism 26, a second conveying frame 30 for connecting the rear tire transfer device and the flipping mechanism 26, and a pushing mechanism 31 for pushing the tire; the first conveying frame 29 has a second conveying channel 32 with a width not less than the axial thickness of the tire. To reduce the friction between the tire and the second conveying channel 32, roller shafts are respectively provided on the left and right side walls of the second conveying channel 32, and a fourth avoidance groove 33 is provided on the bottom surface at the end of the second conveying channel 32; the second conveying frame 30 has a third conveying channel 34 with a length not less than the radial length of the tire.

The distance between the two groups of retaining roller shafts 36 is adapted to the diameter of the tire. The second support frame 37 is connected to a fourth driving mechanism 38 for driving the flipping mechanism 26 to rotate. The second support frame 37 can rotate from a position fitted in the third avoidance groove 12 to a position fitted in the fourth avoidance groove 33. During operation, the second support frame 37 is first fitted in the third avoidance groove 12. At this time, the space inside the second support frame 37 is communicated with the second conveying channel 32. The tire enters the inside of the second support frame 37, and the first tire wall surface 27 is attached to the second support frame 37. Then, the second support frame 37 starts to rotate until it is fitted in the fifth avoidance groove 35. At this time, the space inside the second support frame 37 is communicated with the third conveying channel 34, and the second tire wall surface 28 faces upward.

[0052] To improve the applicable range of the flipping mechanism 26 for tires of different diameters, a group of retaining roller shafts 36 at the upper end of the second support frame 37 is set to be height-adjustable.

[0053] The pushing mechanism 31 includes a vertically arranged pushing plate 39 and a fifth linear telescopic mechanism 40 connected to the pushing plate 39. The pushing plate 39 is located on the side of the fourth avoidance groove 33 away from the second support frame 37. The length of the pushing plate 39 is not less than the radius of the tire. The telescopic direction of the fifth linear telescopic mechanism 40 is consistent with the direction of the line connecting the pushing plate 39 and the second support frame 37, and the telescopic length of the fifth linear telescopic mechanism 40 is not less than the distance between the first tire wall surface 27 and the second support frame 37.

The pushing plate 39 is connected to the fifth linear telescopic mechanism 40 through a bracket 43, and the bracket 43 and the second base 42 are connected through a slide rail. By extending the telescopic end of the fifth linear telescopic mechanism 40, the pushing plate 39 is driven to push the tire to move, so that the first tire wall surface 27 is attached to the second support frame 37.

[0054] The first linear telescopic mechanism 14, the second linear telescopic mechanism 17, the third linear telescopic mechanism 23, the fourth linear telescopic mechanism, and the fifth linear telescopic mechanism 40 can all be components capable of linear telescoping, such as electric push rods and hydraulic cylinders. As a preferred embodiment, the linear telescopic mechanisms mentioned in the present invention are all electric push rods.

[0055] A baffle 41 for blocking the movement of the tire is further provided at the end of the second conveying channel 32. The baffle 41 is inclinedly arranged at the intersection of the bottom surface of the second conveying channel 32 and the back.
