Description

Technical Field

[0001] The present invention relates to the field of tire conveying equipment, and particularly to a device for increasing the supporting surface during the conveying of narrow-edge tires and a tire conveyor. Background Art

[0002] The information disclosed in the background art of the present invention is only intended to increase the overall understanding of the present invention, and is not necessarily regarded as an admission or an indication in any form that this information constitutes the prior art already known to those of ordinary skill in the art.

[0003] During the process of tire uniformity or dynamic balance testing, it is necessary to transfer the tire from a conveyor (such as the input conveyor used in the tire testing system disclosed in the patent document with the application number 98801981.7) to the fixture at the testing station. During the transfer process, the tire is placed flat between two transfer arms, and the belt on the transfer arms drives the tire, thereby realizing the movement of the tire. Since the distance between the transfer arms can be adjusted, the conveying of tires with different diameters can be realized.

[0004] However, the inventor of the present invention found that: due to the limitation of the working environment, the width of the transfer arms and the belt is relatively narrow (about 50 mm). When this kind of tire conveyor transports high aspect ratio tires (i.e., narrow-edge tires), the contact surface between the tire and the transfer arms is small. If the tire is not placed centered or shifted during the transfer due to vibration, during the process of the transfer arms descending, the inner ring of the tire contacts the fixture unevenly, resulting in the tire shifting. At this time, due to the small contact surface between the tire and the transfer arms, sufficient support cannot be provided, and finally the tire falls out of the fixture plane, causing the testing machine to stop working. Summary of the Invention

[0005] In view of the above problems, the present invention provides a device for increasing the supporting surface during the conveying of narrow-edge tires. This device can not only effectively increase the support for the tire, but also keep in synchronous movement with the belt under the action of the conveyor belt, achieving the purpose of jointly conveying the tire with the conveyor belt. To achieve the above object, the technical solution of the present invention is as follows.

[0006] In the first aspect of the present invention, a device for increasing the supporting surface during the conveying of narrow-edge tires is disclosed, including: a mounting plate, a first driving wheel, a second driving wheel, a first driven wheel, a second driven wheel, a synchronous belt, and a supporting wheel, wherein: the first driving wheel and the second driving wheel are movably installed on the front and back surfaces of the mounting plate through a common shaft, the first driven wheel and the second driven wheel are both movably connected to the front surface of the mounting plate, and the first driven wheel and the second driven wheel are both on the same horizontal line above the first driving wheel. The synchronous belt is annular, and it is sleeved on the outer surfaces of the first driving wheel, the second driving wheel, and the first driven wheel to make the synchronous belt in a triangular shape. The supporting wheel is movably connected to the back surface of the mounting plate side by side with the second driving wheel.

[0007] Further, there are two sets of the support wheels, which are respectively distributed on both sides of the second driving wheel. Through the cooperation among the support wheels, the second driving wheel and the conveyor belt of the tire conveying device, synchronous transmission between the synchronous belt and the conveyor belt can be achieved.

[0008] Further, both the first driving wheel and the second driving wheel are gears, so as to facilitate better power transmission.

[0009] Further, the surfaces of the first driven wheel, the second driven wheel and the support wheels are all smooth surfaces, so as to reduce the friction with the synchronous belt and the conveyor belt.

[0010] Further, the mounting plate is provided with a plurality of mounting holes, so as to facilitate the mounting of the driving wheels, driven wheels and support wheels and fix the mounting plate on the conveying arm of the tire conveyor.

[0011] In the second aspect of the present invention, a tire conveyor is disclosed, which includes a bracket, a conveying arm, a conveyor belt and the device for increasing the supporting surface during the conveying of narrow-edge tires. Among them: the conveying arm is horizontally fixed on the bracket, and the two conveying arms are arranged in parallel. The device for increasing the supporting surface during the conveying of narrow-edge tires is vertically fixed on the conveying arm through its mounting plate, and the synchronous belt is located inside the conveying arm, and the second driving wheel and the support wheels are both located below the conveying arm. The two ends of the conveying arm are connected with driving wheels, the conveyor belt is sleeved on the driving wheels and the conveying arm is located between the upper part and the lower part of the conveyor belt. The lower part of the conveyor belt passes between the second driving wheel and the support wheels, and the conveyor belt is in contact with both the second driving wheel and the support wheels. The upper part of the conveyor belt is flush with the synchronous belt.

[0012] Further, when a support wheel is connected to both sides of the second driving wheel, the lower part of the conveyor belt sequentially passes through the gap between the first support wheel and the second driving wheel, and then passes through the gap between the second support wheel and the second driving wheel, so that the conveyor belt forms a "U" shape or an inverted "U" shape here, so as to facilitate the conveyor belt to drive the second driving wheel to rotate.

[0013] Further, the device for increasing the supporting surface during the conveying of narrow-edge tires is arranged on both of the two conveying arms, and the devices for increasing the supporting surface during the conveying of narrow-edge tires on the two conveying arms are symmetrically distributed.

[0014] Further, the driving wheel is connected with a driving motor through a driving shaft, so as to provide driving force for the transmission of the conveyor belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: After the device for increasing the support surface during the transportation of narrow-edge tires of the present invention is installed on the conveyor arm of the conveyor, through the special cooperation with the conveyor belt, not only can the tire be supported by the synchronous belt, reducing the number of times the tire drops, reducing the number of times the equipment stops, and improving the usage efficiency of the equipment. Moreover, driven by the conveyor belt, the synchronous belt moves synchronously with the conveyor belt, so that while supporting the tire, it can also convey the tire synchronously with the conveyor belt, avoiding the problem of increasing the transportation resistance caused by only adding a static support surface, and even causing the tire to be offset due to the unbalanced frictional force between the tire and the static support surface, and then falling off the conveyor belt.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] As mentioned above, when the existing tire conveyor is conveying a high aspect ratio tire, the contact surface between the tire and the conveying arm is small and cannot provide sufficient support, which easily causes the tire to fall out of the clamp plane and cause the test machine to stop working. Therefore, the present invention proposes a device for increasing the support surface during the conveying process of narrow-edge tires, referring to Figure 1 and Figure 2 , the device for increasing the support surface during the transportation of narrow tires shown in the figure is an assembly formed by multiple components including a mounting plate 1, a first driving wheel 2, a second driving wheel 3, a first driven wheel 4, a second driven wheel 5, a synchronous belt 6 and a supporting wheel 7. The above components constitute the basic structure of the device for increasing the support surface during the transportation of narrow tires. In addition, the use of concepts should not be simply understood literally, but should be reflected by their role in specific applications.

[0028] Based on the above problems to be solved and the objectives to be achieved, the device for increasing the supporting surface during the transportation of narrow-edge tires is now described in detail through the following specific embodiments.

[0029] The mounting plate 1 is a metal plate, such as an aluminum alloy plate or a steel plate, and a plurality of mounting holes are provided on its surface to facilitate the installation of each of the driving wheel, driven wheel and supporting wheel, and the mounting plate 1 is fixed to the conveying arm of the tire conveyor.

[0030] The first driving wheel 2 and the second driving wheel 3 are both gears, and the two are movably installed on the front and back of the mounting plate 1 through a common rotating shaft. The first driven wheel 4 and the second driven wheel 5 are both movably connected to the front of the mounting plate 1 through rotating shafts, and the first driven wheel 4 and the second driven wheel 5 are both on the same horizontal line above the first driving wheel 2 to ensure that the synchronous belt 6 is kept horizontal after installation, so as to maintain good contact and support with the horizontally conveyed tire.

[0031] The synchronous belt 6 is a ring structure made of rubber material, and it is sleeved on the outer surfaces of the first driving wheel 2, the second driving wheel 3, and the first driven wheel 4 to make the synchronous belt 6 in a triangular shape. The supporting wheel 7 is movably connected side by side with the second driving wheel 3 on the back of the mounting plate 1, and there are two groups of supporting wheels 7, which are respectively distributed on both sides of the second driving wheel 3. Through the cooperation between the supporting wheel 7, the second driving wheel 3 and the conveyor belt of the tire conveying device, synchronous transmission between the synchronous belt 6 and the conveyor belt can be achieved. The surfaces of the first driven wheel 4, the second driven wheel 5 and the supporting wheel 7 are all smooth surfaces to reduce the friction with the synchronous belt 6 and the conveyor belt.

[0032] Further, referring to Figure 3 and Figure 4 , an example of a tire conveyor is provided, which includes a bracket 8, a conveying arm 9, a conveyor belt 10 and the device for increasing the supporting surface during the conveying of narrow-edge tires, wherein:

[0033] The bracket 8 is vertically fixed on the ground, the conveying arm 9 is horizontally fixed on the bracket 8, and there are two parallel conveying arms 9, and the space between the two conveying arms 9 is hollow.

[0034] Figure 1 and Figure 2 The device for increasing the supporting surface during the conveying of narrow-edge tires shown in the figure is vertically fixed on the conveying arm 9 through its mounting plate 1. Specifically, the mounting plate 6 is detachably fixed on the conveying arm 9 by bolts, and the synchronous belt 6 is located inside the conveying arm 9, while the second driving wheel 3 and the supporting wheel 7 are both located below the conveying arm 9. The device for increasing the supporting surface during the conveying of narrow-edge tires is provided on both of the two conveying arms 9, and the devices for increasing the supporting surface during the conveying of narrow-edge tires on the two conveying arms 9 are symmetrically distributed. It should be noted that the specific number of the devices for increasing the supporting surface during the conveying of narrow-edge tires can be determined according to actual needs or the length of the conveying arm 9, etc.

[0035] Both ends of the transfer arm 9 are connected with drive wheels 11. The drive wheels 11 are connected to a drive motor through drive shafts 12, and the drive wheels 11 on the two transfer arms 9 are both connected to the drive motor through drive shafts 12, so as to ensure that the conveyor belts 10 on the two transfer arms 9 run synchronously. The conveyor belt 10 is sleeved on the drive wheels 11 and the transfer arm 9 is located between the upper part and the lower part of the conveyor belt 10. The upper part of the conveyor belt 10 is flush with the timing belt 6. Driven by the conveyor belt 10, the timing belt 6 moves synchronously with the conveyor belt 10, so that while supporting the tire, it can also convey the tire synchronously with the conveyor belt 10, avoiding the problem that the transportation resistance is increased due to only increasing the static support surface, and even the tire is subjected to uneven friction force between the static support surface, resulting in the tire shifting and then falling off the conveyor belt.

[0036] A support wheel 7 is connected to both sides of the second driving wheel 3. The lower part of the conveyor belt 10 passes through the gap between the first support wheel 7 and the second driving wheel 3 in sequence, and then passes through the gap between the second support wheel 7 and the second driving wheel 3, so that the conveyor belt 10 forms a "U" shape or an inverted "U" shape here, and the conveyor belt 10 is in contact with both the second driving wheel 3 and the support wheel 7, so as to facilitate the conveyor belt 10 to drive the second driving wheel 3 to rotate. After this device for increasing the support surface during the transportation of narrow-edge tires is installed on the transfer arm 9 of the conveyor, through the special cooperation between the support wheel 7, the second driving wheel 3 and the conveyor belt 10, the synchronous transmission of the timing belt 6 and the conveyor belt can be realized, and then the tire can be conveyed together with the conveyor belt. At the same time, the support formed by the timing belt 6 for the tire can effectively reduce the number of tire drops, reduce the number of equipment shutdowns, and improve the use efficiency of the equipment.

[0037] Finally, it should be noted that any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention.
