Description

Technical Field

[0001] The utility model relates to the field of automobile production, in particular to a turnover mechanism. Background Art

[0002] In the field of modern automobile production, the distribution and handling of tires is an important part of the production line. Traditionally, tires are delivered directly to the edge of the production line through a conveyor line, and then they need to be flipped from a flat state to a vertical state through a specific flipping mechanism so that the robot arm can take the tire and perform subsequent installation work.

[0003] The existing flipping mechanism usually sets a 90-degree flipping machine at the end of the conveyor line, and the tire is conveyed to the end in the horizontal direction through the accumulation roller driven by the horizontal motor. When the tire reaches the end, another flipping motor drives the flipping mechanism to flip the tire to a position where the robot arm can take the tire.

[0004] However, this method requires the installation of a horizontal drive motor to complete the horizontal position of the tire, which increases the complexity of the equipment and the production cost. At the same time, after flipping into place, since only a straight-shaped limit rod is provided at the end of the flipping mechanism, the front end of the tire is unobstructed after flipping, and there is a risk of rollover, which may further damage the tire or increase manual operation time.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1-2 A turning mechanism is arranged at the end of a tire conveying line 1 and is used for turning over a tire. The turning mechanism comprises a fixed frame 2, a turning driving device 3, a turning roller 4 and a blocking unit 5. The fixed frame 2 is provided with a turning driving device 3, and the turning driving device 3 is provided with a turning roller 4. The turning driving device 3 can drive the turning roller 4 to turn over, so that the turning roller 4 can be switched between a horizontal state and a vertical state. The top surface of the turning roller 4 can make the tire, when it leaves the tire conveying line 1, overcome the friction between the turning roller 4 and the tire under the action of inertia and be transported downward to the end of the turning roller 4, so as to realize the automatic advancement of the tire in the horizontal advancing direction, reduce the demand for the horizontal conveying motor, and thus reduce the investment required for production.

[0022] A blocking unit 5 is provided on the side of the turning roller 4 away from the tire conveying line 1. The blocking unit 5 includes two L-shaped blocking rods 51. The two blocking rods 51 are symmetrically arranged on the side of the turning roller 4 away from the tire conveying line 1. The movement of the tire in two directions can be restricted when the turning roller 4 is in a horizontal and vertical state, thereby preventing the tire from rolling over on the turning roller 4.

[0023] The turning drive device 3 includes a driving motor 31 fixed on the fixing frame 2. The fixing frame 2 is provided with a turning seat on the side away from the tire conveying line 1. A rotatable turning shaft 32 is penetrated by the turning seat. A turning block 33 is provided on the turning shaft 32. The turning shaft 32 is connected to the driving motor 31 by transmission. A turning roller 4 is provided on the turning block 33. The turning shaft 32 is driven by the driving motor 31 to rotate, thereby driving the turning block 33 to rotate, thereby realizing the turning of the tire on the turning roller 4.

[0024] The turning roller 4 includes a turning frame 41 fixed on the turning drive device 3, and at least three rollers 42 are arranged on the turning frame 41. The fixed unpowered roller section 6 includes a first support block 61 and a second support block 62 fixed on the fixed frame 2. The first support block 61 and the second support block 62 are arranged in parallel. Two inclined plates 63 are arranged on the top of the first support block 61 and the second support block 62. At least two unpowered rollers 64 are arranged between the two inclined plates 63. The first support block 61 is arranged lower than the second support block 62, so that the two inclined plates 63 can be inclined, so that the multiple unpowered rollers 64 form an inclined surface. The rollers 42 and the unpowered rollers 64 can reduce the friction between the tire and the turning roller 4 and the fixed unpowered roller section 6, so as to facilitate the automatic movement of the tire in the horizontal direction.

[0025] In some embodiments, a fixed unpowered roller section 6 is further provided on the fixed frame 2, and the fixed unpowered roller section 6 is provided between the end of the tire conveying line 1 and the turning roller 4, and the top surface of the fixed unpowered roller section 6 and the top surface of the turning roller 4 are located on the same inclined plane; when the tire leaves the tire conveying line 1, it overcomes the friction between the fixed unpowered roller section 6 and the tire under the action of inertia and is automatically transported downward to reach the turning roller 4, which can realize the reserve of tires leaving the tire conveying line 1 and reserve working time for the turning of the turning roller 4, thereby improving the continuity of the turning work.

[0026] In some embodiments, a limit block 7 is also provided on the fixed frame 2, which can support the flip roller 4 close to the tire conveyor line 1 when the flip roller 4 is in a horizontal state, thereby improving the stability of the flip roller 4 and reducing the pressure on the flip drive device 3 to extend its service life.

[0027] In some embodiments, an in-place detection sensor is provided on the blocking unit 5, and the in-place detection sensor is connected to the flipping drive device 3. The in-place detection sensor detects that the tire has moved into place, and immediately starts the flipping drive device 3, thereby realizing the flipping of the tire, realizing the automatic control of the flipping mechanism, and improving the flipping efficiency.

[0028] In some embodiments, the angle between the top surface of the flip roller 4 and the horizontal plane can be 10°-20°, which can allow the tire to move smoothly to the end of the flip roller 4, avoiding excessive movement speed and causing the tire to fall from the flip roller 4 and the fixed unpowered roller section 6 during automatic advancement.

[0029] The specific working principle is as follows:

[0030] The tire leaves the tire conveyor line 1 and falls onto the fixed non-powered roller section 6. Under the action of the tire inertia, its own gravity and the inclination angle of the fixed non-powered roller section 6, the tire automatically moves toward the flip roller 4. When it moves onto the flip roller 4, the tire automatically continues to move to the end of the flip roller 4 and touches the two blocking rods 51. The two blocking rods 51 restrict the tire from continuing to move. At the same time, the in-place detection sensor detects that the tire has moved into place, and the drive motor 31 is started to drive the flip roller 4 to move, thereby realizing the flipping of the tire. During the flipping process, the two blocking rods 51 always restrict the movement of the tire in two directions, thereby effectively preventing the tire from rolling over during the flipping process.
