Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] For the convenience of description, the following uses specific devices to describe the present invention. For example, the first transportation component uses the third roller machine 9, the tire tread arrangement component uses the mesh belt component 11, and the second transportation component uses the fourth roller machine 13; those of ordinary skill in the art should understand that the use of the specific structures of the above first transportation component, second transportation component, and tire tread arrangement component does not exclude the use of structures with the same or similar functions. As long as the components that can achieve substantially the same functions belong to the equivalent replacement of the above components.

[0024] Figure 1 、 2, 3. Disclosed is a tire tread automatic collection system according to an embodiment of the present application, including a centering conveying device 1 for conveying a steel-belted tire tread 8 downstream along the length direction X of the steel-belted tire tread 8 in an automatically centered manner. At the tail end of the centering conveying device 1 in its conveying direction, there is a tread picking-up device 2 for receiving the steel-belted tire tread 8 conveyed from the centering conveying device 1. The tread picking-up device 2 includes a third roller machine 9, a mesh belt assembly 11, a first tread transfer device 10, and a second tread transfer device 12. Among them, the third roller machine 9 receives the steel-belted tire tread and can continue to convey the steel-belted tire tread 8 along the length direction X. The mesh belt assembly 11 is arranged in the direction Y orthogonal to the length direction X for receiving the steel-belted tire tread 8 from the first tread transfer device 10 and arranging multiple steel-belted tire treads 8 at equal intervals to form a steel-belted tire tread group 80. The first tread transfer device 10 is arranged below the first roller machine 3 and / or the mesh belt assembly 11, and is used for lifting the steel-belted tire tread 8 from the first roller machine 3 and moving it along the Y direction and placing the steel-belted tire tread 8 on the mesh belt of the mesh belt assembly 11. The second tread transfer device 12 is configured to lift the steel-belted tire tread group 80 from the mesh belt of the mesh belt assembly 11 and transport the steel-belted tire tread group 80 along the Y direction to the fourth roller machine 13.

[0025] In Figure 2 the illustrated embodiment, the lower part of the tread picking-up device 2 is fixed to a frame 14, which includes a third power roller machine 9, and a first tread transfer device 10 is arranged below the third power roller machine 9.

[0026] The first tread transfer device 10 has a structure as Figure 3As shown, it includes a tire positioning device 10. The tire positioning device 10.1 includes a plurality of parallel brackets 10.1.1. The plurality of parallel brackets are arranged on a base 10.1.2. The base 10.1.2 is coupled to a carriage 10.1.3. The base 10.1.2 is configured to move up and down relative to the carriage 10.1.3. For example, the base 102 is driven by a first cylinder assembly 10.1 mounted on the carriage 10.1.3 to move up and down relative to the carriage 10.1.3. And the base 10.1.2 is configured to be slidable along a guide rail assembly 10.2 parallel to the extending direction of the brackets 10.1.1. For example, through the carriage 10.1.3 at the lower part of the base and a second cylinder assembly 10.4 that drives the carriage 10.1.3 to act, the base 10.1.2 can slide on the guide rail assembly 10.2. Thus, the tire positioning device 10.1 can move as a whole along the guide rail assembly 10.2 in a direction orthogonal to the all-steel tire tread. The guide rail assembly 10.2 can be two guide rails symmetrically arranged at the bottom of the carriage 10.1.3 and mounted on brackets 10.5. The length of the brackets 10.5 and / or the guide rail assembly 10.2 is configured such that the brackets 10.1.1 of the tire positioning device 10.1 can be translated under the third roller machine 9 and the mesh belt assembly 11. The plurality of brackets 10.1.1 are arranged in parallel at intervals. This interval allows the brackets 10.1.1 to extend out of the interval between the rollers of the third power roller machine to a height higher than the horizontal height of the rollers when the base 10.1.2 is driven by the first cylinder assembly to rise, and move between the intervals of the mesh belt of the mesh belt assembly 11.

[0027] The mesh belt assembly 11 mainly consists of a mesh belt, a mesh belt bracket for supporting the mesh belt, a mesh belt driving part for driving the mesh belt to move, and a frame for mounting the above-mentioned mesh belt, bracket, and driving part, etc. Its characteristics are smooth conveying, small friction, long service life, and durability. There is an interval between the mesh belt bracket and the mesh belt, and this interval is aligned with the interval between the rollers of the third power roller machine 9. Such a setting enables the tire positioning device 10.1 to move between the third power roller machine 9 and the mesh belt assembly.

[0028] The mesh belt driving part of the mesh belt assembly 11 can be driven by a Siemens servo motor, for example, to drive the mesh belt through a transmission shaft and a driving wheel. For example, the diameter d of the driving wheel = 151mm, and the rotation angle of the driving motor = 50mm / (151*3.14)x360 degrees = 37.9 degrees. It can be seen from this that for every 37.9 degrees of rotation of the motor, the tire tread moves a displacement of 50mm.

[0029] The first power roller machine 3, the second power roller machine 4, the third power roller machine 9, and the fourth power roller machine 13 can all adopt the form of a roller line. The roller line is suitable for transporting items with a flat bottom and is mainly composed of driving rollers, a frame, brackets, a driving part, etc. It has the characteristics of large conveying volume, high speed, light operation, and the ability to achieve multi-variety conveying. Multiple rollers on the roller line are arranged in a row, and each roller has a driving sprocket. The driving sprocket is connected to the driving motor through a chain to drive the roller to rotate, playing a role in transporting the tread.

[0030] The automatic centering conveying device 1 can be composed of two roller lines. Among them, the two rows of rollers are arranged at an angle. The tread is guided starting from when it enters the roller line. The all-steel tread 8 enters from the left, and the left roller gives the all-steel tread 8 a force to the right, pushing the all-steel tread 8 to the middle of the automatic centering conveying device. When the all-steel tread enters from the right, the left roller gives the all-steel tread 8 a force to the left, pushing the all-steel tread 8 to the middle of the automatic centering conveying device, ensuring that the all-steel tread enters the longitudinal middle of the centering device.

[0031] The collection system of this embodiment further includes a second tread transfer device 12. This device includes a tread group handling device enabled to transport the all-steel tread group in the Y direction to the fourth power roller machine 13. This handling device can be designed to have the same structure as the above-mentioned tire placing device 10.1, that is, it has multiple brackets, a base for fixing the brackets in parallel, a carriage for installing the base, a cylinder assembly for driving the base to vertically leave the carriage, a guide rail for installing the carriage so that the carriage can slide in the horizontal direction, a cylinder assembly for driving the carriage to move on the guide rail, and a frame for installing the tread group handling device. Here, the brackets of the tread group handling device are designed to have a wider width so that it can lift an all-steel tread group composed of multiple all-steel treads at one time, such as three all-steel treads, and then transport the all-steel tread group to the fourth power roller machine 13 at one time, and then the fourth power roller machine 13 continues to transport the all-steel tread group in the X direction.

[0032] In this embodiment, the front detection device includes a sequentially arranged all-steel detection part, a contour measurement part, and a quality detection part. Before the all-steel tread 8 is transported to the tread automatic collection system, it first passes through a metal detection device. The standard of the metal detection device is: non-ferrous all-steel less than φ5mm, ferrous all-steel less than φ3mm, and the conveyor belt speed ≥ 1.5m / min is qualified, otherwise it is unqualified. Then it passes through a contour measurement system. If the thickness deviation of the tread 8 is less than the set value, it is qualified, otherwise it is unqualified. Finally, it passes through a weighing device. If the weight deviation of the tread 8 is less than the set value, it is qualified, otherwise it is unqualified. Unqualified all-steel tread products are transported to the non-conforming product collection part 6 by the first roller machine 3 for temporary storage. After reaching a certain quantity, they are recycled to the extruder for reuse to avoid waste of the rubber compound.

[0033] The control process of the tire placing device 10.1 is as follows: When receiving the signal that the all-steel tire tread 8 conveyed by the third power roller machine 9 is a qualified all-steel tire tread, the first cylinder assembly 10.3 responsible for the up and down movement of the tire placing device 10.1 of the first tire tread transfer device 10 is controlled to act, pushing the tire placing device 10.1 of the first tire tread transfer device 10 upward to disengage the all-steel tire tread 8 from the third power roller machine 9; then the second cylinder assembly 10.4 responsible for the left and right movement of the tire placing device 10.1 of the first tire tread transfer device 10 is controlled to act, causing the tire placing device 10.1 of the first tire tread transfer device 10 to move along the guide rail assembly 10.2 towards the mesh belt 11, transporting the all-steel tire tread 8 above the mesh belt 11, and then the cylinder 10.3 responsible for the up and down movement of the tire placing device of the first tire tread transfer device is controlled to act, pushing the tire placing device 10.1 of the first tire tread transfer device downward, disengaging the all-steel tire tread 8 from the tire placing device 10.1 of the first tire tread transfer device, and placing it on the mesh belt of the mesh belt assembly 11. After that, the tire placing device 10.1 of the first tire tread transfer device 10 is controlled to move along the guide rail assembly 10.2 to wait below the third power roller machine 9.

[0034] The second tire tread transfer device 12 is arranged below the mesh belt assembly 11. It has a structure similar to that of the tire placing device 10.1, that is, it includes the cylinder action responsible for the up and down movement of the second tire tread transfer device, pushing the second tire tread transfer device upward to disengage the three all-steel tire treads from the mesh belt. The cylinder action responsible for the left and right movement of the second tire tread transfer device acts to cause the second tire tread transfer device to move towards the fourth roller line, transporting the all-steel tire tread above the fourth roller line 13. The cylinder action responsible for the up and down movement of the second tire tread transfer device acts to push the second tire tread transfer device downward, disengaging the all-steel tire tread from the second tire tread transfer device, and placing it on the fourth roller line. The second tire tread transfer device moves to wait below the mesh belt.

[0035] After the weighed all-steel tread 8 is automatically centered by the centering conveying device 1, it is conveyed to the third power roller machine 9 of the tread picking device 2, and its lower part is the frame 14; the first tread transfer device 10 is arranged below the first power roller machine 9. When all the detection devices determine that the all-steel tread 8 is qualified, the cylinder responsible for the up and down movement of the first tread transfer device 10 acts to push the first tread transfer device 10 upward, so that the all-steel tread 8 is separated from the first power roller machine 9. The cylinder responsible for the left and right movement of the first tread transfer device 10 acts to make the first tread transfer device 10 move towards the mesh belt 11, transport the all-steel tread 8 above the mesh belt 11, and the cylinder responsible for the up and down movement of the first tread transfer device 10 acts to push the first tread transfer device 10 downward, and the all-steel tread 8 is separated from the first tread transfer device 10 and placed on the mesh belt 11. The first tread transfer device 10 moves below the first power roller machine 9 and waits. The mesh belt 11 moves a distance of the all-steel tread width + 50 mm in the direction of the second power roller machine 13, creating a vacancy for the all-steel tread 8 between the mesh belt 11 and the first power roller machine 9. The first tread transfer device 10 repeats the above actions to transfer the second all-steel tread 8 from below the first power roller machine 9 onto the mesh belt 11. The mesh belt 11 then moves a distance of the all-steel tread 8 width + 50 mm in the direction of the second power roller machine 13, and the first tread transfer device 10 transfers the third all-steel tread 8 from the roller line of the first tread transfer device 10 onto the mesh belt 11. In this way, the three all-steel treads 8 are neatly arranged on the mesh belt 11, and the mesh belt 11 transports the three treads 8 to the head; the second tread transfer device 12 transfers the tread 8 from the mesh belt 11 to the second power roller machine 13, and thus the tread 8 picking action is completed.

[0036] Preferably, after the first tread transfer device transfers a single all-steel tread from the third power roller machine 9 of the tread picking device 2 to the mesh belt assembly 11 of the tread picking device 2, the controller controls the mesh belt line motor to rotate 37.9 degrees, causing the tread to move a displacement of 50 mm. The operating speeds of all devices are the same, the tread runs at a constant speed, the kinetic energy remains unchanged, and the external force on the tread in the horizontal direction is zero, so the tread does not move on each device.

[0037] In some embodiments, a second roller machine 4 may further be included, which is disposed downstream of the second power roller machine 13 of the tread picking device 2 and transports the all-steel tread group in matching with the second power roller machine 13. A grille vehicle 7 is provided at the tail end of the second roller machine 4; a mobile conveying device 5 matching with the grille vehicle 7 may also be provided. The grille vehicle has multiple layers. The controller controls the second power roller machine 13 to transport the tread 8 to the second roller machine 4. The mobile conveying device 5 moves into the grille vehicle 7. The second roller machine 4 operates to transport the arranged three-piece all-steel tread group into the grille vehicle 7. The mobile conveying device 5 transports the all-steel tread 8 to the uppermost layer of the grille vehicle 7. The grille vehicle 7 moves upward by one station for arranging and layering. The second roller machine 4 and the mobile conveying device 5 operate simultaneously to transport the arranged three-piece all-steel tread 8 to the second layer of the grille vehicle 7. The above actions are repeated until the grille vehicle 7 is completely filled.

[0038] The systems and devices in the present invention are preferably applicable to the collection of the treads of radial truck tires (TBR). It should be understood that they may also be applicable to the collection of the treads of other vehicle tires as long as they have similar characteristics.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
