Description

Technical Field

[0001] This invention relates to the field of rubber tire manufacturing technology, and in particular to an automated production line for triangular rubber bead production lines. Background Technology

[0002] The tire bead, as the supporting skeleton of the tire, is one of the key components of the tire structure. A tire bead typically consists of a hexagonal steel wire ring and a triangular rubber core. To ensure the dynamic and static balance and service life of the tire, the manufacturing process of the tire bead must guarantee the fit quality between the triangular rubber core and the steel wire ring, as well as the connection precision at the rubber core joint.

[0003] In related technologies, systems used for the production of triangular rubber tire beads are often distributed in a decentralized manner, requiring manual coordination between various processes. This not only results in a large footprint, high labor intensity, and low production efficiency, but also insufficient automation, which cannot guarantee the consistency of quality in batch production of triangular rubber tire beads. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose an automated production line for triangular rubber tire beads. This automated production line can realize the automated production of triangular rubber tire beads, with high production efficiency, low labor costs, and can ensure the consistency of quality in batch production of triangular rubber tire beads.

[0006] An automated production line for triangular rubber bead according to an embodiment of the present invention includes a triangular rubber forming system, a wire bead forming system, and a bead forming system. The triangular rubber forming system is connected to the bead forming system. The triangular rubber forming system is adapted to form triangular rubber and can transport the triangular rubber to the bead forming system. The wire bead forming system is connected to the bead forming system through a first actuator. The wire bead forming system is adapted to form finished bead rings. The first actuator can move the finished bead rings to the bead forming system so that the bead forming system can attach the triangular rubber to the finished bead rings to form finished bead rings.

[0007] The automated production line for triangular rubber tire bead according to an embodiment of the present invention integrates a triangular rubber forming system, a wire bead forming system, and a tire bead forming system to construct the entire production line for triangular rubber tire bead. The triangular rubber forming system transports the triangular rubber to the tire bead forming system, while a first actuator transfers the finished bead formed by the wire bead forming system to the tire bead forming system. This allows the tire bead forming system to attach the triangular rubber to the finished bead to produce the finished tire bead, thereby achieving automated coordination and connection between the various processes of the entire line. Therefore, compared with related technologies, the present invention can achieve automated production of triangular rubber tire bead, with high production efficiency, low labor costs, and can ensure the consistency of quality in batch production of triangular rubber tire bead.

[0008] In some embodiments, the production line further includes a bead stacking conveyor system, which is connected to the bead forming system via the first actuator. The first actuator is capable of moving finished bead sheets to the bead stacking conveyor system for stacking and storage, so that the bead stacking conveyor system can transfer the finished bead sheets.

[0009] In some embodiments, the tire bead stacking conveying system includes a first conveyor line and a material trolley. The first conveyor line has an entry position, a stacking position, and an exit position. The material trolley is connected to the first conveyor line and is adapted to flow sequentially between the entry position, the stacking position, and the exit position. The material trolley can connect with the first actuator at the stacking position so that the first actuator can stack finished tire bead pieces on the material trolley.

[0010] In some embodiments, the bead stacking conveying system further includes a spacer gripping device adapted to pick up and place spacers and capable of engaging with the material trolley at the stacking position to facilitate the placement of spacers between any two adjacent finished bead stacks.

[0011] In some embodiments, the first conveyor line further includes a gripping position, wherein the entry position, the gripping position, the stacking position, and the exit position are arranged sequentially along the conveying direction of the first conveyor line, and there are at least two material trolleys. When one material trolley switches from the entry position to the gripping position, the other material trolley switches from the gripping position to the stacking position. The material trolley can carry a spacer at the gripping position and connect with the spacer gripping device so that the spacer gripping device can grip the spacer.

[0012] In some embodiments, the diaphragm gripping device includes a main frame, a mounting base, a lifting drive, a swing arm, and diaphragm claws. The mounting base is movably connected to the main frame along the height direction. The lifting drive is mounted on the main frame and drivenly connected to the mounting base to adjust the height position of the mounting base on the main frame. The swing arm is pivotally connected to the mounting base via a rotation drive. The pivot axis of the swing arm is aligned with the height direction to adjust the horizontal position of the swing arm relative to the material cart by the rotation drive. The diaphragm claws are mounted on the swing arm and adapted to connect with the diaphragm.

[0013] In some embodiments, the septum gripping device further includes a gripping probe and a buffer cylinder, both of which are mounted on the swing arm. The gripping probe can trigger a probe signal when the piston rod of the buffer cylinder contacts the septum.

[0014] In some embodiments, the production line further includes a bead joint detection device and a defective conveying device, both of which are connected to the first actuator. The first actuator can move finished bead joints to the bead joint detection device to detect the joints of the finished bead joints, and the defective conveying device is used to transfer defective finished bead joints.

[0015] In some embodiments, the bead joint detection device includes a base, a detection disc, and a camera. The detection disc is pivotally mounted on the base and has a detection area. A first actuator is connected to the detection disc and can move a finished bead to the detection disc. The camera is movably connected to the base and has a detection position and an idle position. When the camera switches from the idle position to the detection position, the camera is located in the detection area. The detection disc can rotate the bead joint of the finished bead to the detection area so that the camera can acquire image information of the bead joint. The camera is spaced apart from the detection area in the idle position so that the first actuator can transfer the finished bead.

[0016] In some embodiments, the triangular rubber forming system includes a triangular rubber composite extruder, a first detection unit, a triangular rubber cooling unit, and a second detection unit connected in sequence, wherein the second detection unit is connected to the bead forming system;

[0017] The first detection unit includes at least one of the following arranged in sequence: a receiving and forced shrinking device, a continuous weighing device, a first width measuring device, a pressure and exhaust device, and a first marking device. The second detection unit includes at least one of the following arranged in sequence: a second width measuring device, a final inspection weighing device, and a second marking device. The final inspection weighing device is capable of scanning and weighing the triangular rubber. Both the first marking device and the second marking device are used to mark unqualified triangular rubber segments.

[0018] In some embodiments, a defective product rejection unit is further connected between the second detection unit and the bead forming system. The defective product rejection unit is adapted to reject defective triangular rubber segments. The defective product rejection unit includes a second conveyor line, a cutting device, and a picking mechanism. The second detection unit and the bead forming system are connected via the second conveyor line, which is used to convey triangular rubber. The cutting device and the picking mechanism are both connected to the second conveyor line. The cutting device can cut the triangular rubber to obtain defective triangular rubber segments, and the picking mechanism can pick up and transfer the defective triangular rubber segments.

[0019] In some embodiments, the defective product rejection unit further includes a defective product cart, which is connected to the picking mechanism and is adapted to load defective triangular rubber segments.

[0020] In some embodiments, the triangular glue molding system further includes a first storage device, and the triangular glue cooling unit is connected to the second detection unit through the first storage device. The first storage device is used to temporarily store the triangular glue.

[0021] In some embodiments, the triangular rubber forming system further includes a second storage device, through which the second conveyor line is connected to the bead forming system, and the second storage device is used to temporarily store qualified triangular rubber.

The wire coil wrapping device is connected to the wire winding device via a third actuator and wraps the wire coil with fabric to form a finished coil. The wire coil wrapping device is connected to the second actuator.

[0025] In some embodiments, the triangular rubber forming system, the bead forming system, and the wire bead forming system are arranged sequentially along a first direction. There are two bead forming systems and two wire bead wrapping devices arranged along a second direction at an angle to the first direction. The wire winding device is located between the two wire bead wrapping devices. There are two first actuators that correspond one-to-one with the bead forming system and two second actuators that correspond one-to-one with the wire bead wrapping device.

[0026] In some embodiments, each of the first actuator and the second actuator may be pivotally mounted between the bead forming system and the wheel rim covering device, with the first actuator being closer to the bead forming system than the second actuator.

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1 As shown in the figure, an automated production line for triangular rubber bead of the present invention includes a triangular rubber forming system 1, a wire bead forming system 2, and a bead forming system 3. The triangular rubber forming system 1 is connected to the bead forming system 3. The triangular rubber forming system 1 is suitable for forming triangular rubber and can transport the triangular rubber to the bead forming system 3. The wire bead forming system 2 is connected to the bead forming system 3 through a first actuator 4. The wire bead forming system 2 is suitable for forming finished bead rings. The first actuator 4 can move the finished bead rings to the bead forming system 3 so that the bead forming system 3 can attach the triangular rubber to the finished bead rings to form finished bead rings.

[0037] It is understood that the automated production line for triangular rubber tire bead according to the embodiments of the present invention integrates the triangular rubber forming system 1, the wire bead forming system 2, and the tire bead forming system 3 to construct the entire production line for triangular rubber tire bead. The triangular rubber forming system 1 can transport the triangular rubber to the tire bead forming system 3, and the first actuator 4 can transfer the finished bead formed by the wire bead forming system to the tire bead forming system 3, so that the tire bead forming system 3 can attach the triangular rubber to the finished bead to produce the finished tire bead. This realizes the automated coordination and connection between the various processes of the entire line. Therefore, compared with related technologies, the present invention can realize the automated production of triangular rubber tire bead, with high production efficiency, low labor costs, and can ensure the consistency of the quality of batch triangular rubber tire bead production.

[0038] like Figure 1 As shown, in some embodiments, the production line also includes a bead stacking conveyor system 5, which is connected to the bead forming system 3 via a first actuator 4. The first actuator 4 can move finished bead stacks to the bead stacking conveyor system 5 for stacking and storage, so that the bead stacking conveyor system 5 can transfer finished bead stacks.

[0039] Understandably, the method of moving finished tire bead to the tire bead stacking conveyor system 5 by the first actuator 4 not only realizes the automatic unloading and stacking of finished tire bead, further improving the automation performance of the production line, but also reduces the floor space occupied by the entire line by using the same first actuator 4 to realize the flow of finished tire bead and finished tire bead in the whole line.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the tire bead stacking conveying system 5 includes a first conveyor line 51 and a material trolley 52. ​​The first conveyor line 51 has an entry position 511, a stacking position 512 and an exit position 513. The material trolley 52 is connected to the first conveyor line 51 and is adapted to flow sequentially between the entry position 511, the stacking position 512 and the exit position 513. The material trolley 52 can be connected to the first actuator 4 at the stacking position 512 so that the first actuator 4 can stack and store the finished tire bead on the material trolley.

[0041] Understandably, since the material trolley is connected to the first conveyor line 51, the first conveyor line 51 can drive the material trolley to automatically move between the entry position 511, the stacking position 512 and the exit position 513 in sequence. In coordination with the first actuator 4, the production continuity of the entire line is ensured while the automated transfer of finished tire bead is realized.

[0042] like Figure 1 and Figure 2As shown, in some embodiments, the bead stacking conveying system 5 further includes a spacer gripping device 53, which is adapted to pick up and place spacers and can be connected to the material trolley 52 at the stacking position 512, so as to place spacers between any two adjacent finished bead stacks, thereby achieving the separation and stacking of finished bead stacks between them and avoiding the impact of the squeezing force between them on the quality of the finished bead stacks.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the first conveyor line 51 also has a gripping position 514. The entry position 511, gripping position 514, stacking position 512 and exit position 513 are arranged sequentially along the conveying direction of the first conveyor line 51. There are at least two material carts 52. When one material cart 52 switches from the entry position 511 to the gripping position 514, the other material cart 52 switches from the gripping position 514 to the stacking position 512. The material cart 52 can carry the spacer at the gripping position 514 and connect with the spacer gripping device 53 so that the spacer gripping device 53 can grip the spacer.

[0044] It is understandable that integrating the entry position 511, gripping position 514, stacking position 512, and exit position 513 onto the first conveyor line 51 allows the material trolley 52 to move sequentially between each workstation as it moves along the first conveyor line 51. At the same time, the spacer gripping device 53 can grip the spacer from the material trolley 52 on the gripping position 514 and place it on the side material trolley 52 used to carry the finished tire bead, which further improves the structural compactness of the overall line layout.

[0045] Specifically, the first conveyor line 51 is not limited to a conveyor roller conveyor. The material trolley 52 can enter the entry position 511 fully loaded with spacers, and at the gripping position 514, the spacer gripping device 53 transfers the spacers one by one to the material trolley 52 at the stacking position 512 until the material trolley 52 at the gripping position 514 is empty. The material trolley 52 at the stacking position 512, which is full of finished tire bead, moves to the exit position 513, while the empty material trolley 52 at the gripping position 514 enters the stacking position 512 to prepare for the continued stacking of finished tire bead.

[0046] Furthermore, the tire bead stacking conveyor system 5 can be electrically connected to the AGV system for communication, enabling the tire bead stacking conveyor system 5 to have automatic vehicle entry and exit functions. That is, when the material trolley 52 fully loaded with finished tire beads is located at the exit position 513, the tire bead stacking conveyor system 5 feeds back to the AGV system, and the AGV system then removes the material trolley 52 from the position 513. At the same time, when there is no material trolley 52 at the entry position 511, the tire bead stacking conveyor system 5 will also communicate with the AGV system so that the AGV system can send the material trolley 52 fully loaded with spacers into the entry position 511, thereby realizing the automatic transfer of spacers and finished tire bead logistics.

[0047] like Figure 3 As shown, in some embodiments, the diaphragm gripping device 53 includes a main frame 531, a mounting base 532, a lifting drive 533, a swing arm 534, and a diaphragm claw 535. The mounting base 532 is movably connected to the main frame 531 along the height direction. The lifting drive 533 is mounted on the main frame 531 and is drivenly connected to the mounting base 532 to adjust the height position of the mounting base 532 on the main frame 531. The swing arm 534 is pivotally connected to the mounting base 532 via a rotation drive 536. The pivot axis of the swing arm 534 is in the same direction as the height direction so that the horizontal position of the swing arm 534 relative to the material cart 52 can be adjusted by the rotation drive 536. The diaphragm claw 535 is mounted on the swing arm 534 and is adapted to be connected to the diaphragm.

[0048] Understandably, the lifting drive 533 and the rotary drive 536 work together to adjust the position of the swing arm 534 on the main frame 531, so that the spacer claw 535 can grab the spacer from the material cart 52 at the grabbing position 514 and transfer the spacer to the finished tire bead at the stacking position 512, thus completing the automatic picking and placing of the spacer. At the same time, the spacer grabbing device 53 has a vertical structure, which occupies little space, improves space utilization, and has a simple structure and is easy to maintain.

[0049] Specifically, the lifting drive 533 may not be limited to including a motor and a cable chain. The rotary drive 536 may not be limited to a swivel cylinder. The main frame 531 may extend in the height direction, that is, in the vertical direction shown in the figure.

[0050] like Figure 3 As shown, in some embodiments, the septum gripping device 53 further includes a gripping probe and a buffer cylinder. Both the gripping probe and the buffer cylinder are mounted on the swing arm 534. The gripping probe can trigger a probe signal when the piston rod of the buffer cylinder contacts the septum, so as to control the lifting drive 533 to stop driving the mounting base 532 to descend, effectively avoiding the problem that the septum claw 535 may easily damage the septum when the swing arm 534 descends excessively.

[0051] It should be noted that the specific structure and working principle of the grasping probe and the buffer cylinder can adopt existing technologies in this field, and will not be elaborated here.

[0052] Furthermore, the spacer claw 535 is a conical spacer claw 535 and has a guide cone surface. The guide cone surface can be movably connected to the inner circumferential surface of the spacer along the extension direction of the guide cone surface to guide the spacer to be centered and fitted on the spacer claw 535. The guide cone surface structure reduces the contact area with the spacer, reduces the risk of the spacer claw 535 damaging the spacer tooling, and under the guidance of the guide cone surface, the effect of misalignment and uneven stacking caused by individual differences of the spacers can be eliminated.

[0053] like Figure 1 As shown, in some embodiments, the production line further includes a bead joint detection device 6 and a defective conveying device 7. Both the bead joint detection device 6 and the defective conveying device 7 are connected to the first actuator 4. The first actuator 4 can move the finished bead to the bead joint detection device 6 to detect the joint of the finished bead, and the defective conveying device 7 is used to transfer defective finished beads. The defective conveying device 7 is not limited to using a conveyor line.

[0054] Understandably, the tire bead stacking conveyor system 5, tire bead joint detection device 6, and defective conveyor device 7 work together to achieve automatic detection of tire bead joints while meeting production efficiency requirements. This reduces manual intervention, greatly improves the automation level of the entire line, and ensures the production quality of finished tire bead products.

[0055] like Figure 4 As shown, in some embodiments, the tire bead joint detection device 6 includes a base 61, a detection disk 62, and a camera 63. The detection disk 62 is pivotally mounted on the base 61 and has a detection area. The first actuator 4 is connected to the detection disk 62 and can move the finished tire bead to the detection disk 62. The camera 63 is movably connected to the base 61 and has a detection position and an idle position. When the camera 63 switches from the idle position to the detection position, the camera 63 is located in the detection area. The detection disk 62 can rotate the joint of the finished tire bead to the detection area so that the camera 63 can acquire image information of the joint of the finished tire bead. The camera 63 is spaced apart from the detection area in the idle position so that the first actuator 4 can transfer the finished tire bead.

[0056] Understandably, after the first actuator 4 places the finished tire bead produced by the tire bead forming system 3 onto the inspection plate 62, the inspection plate 62 can rotate the joint of the finished tire bead to the inspection area, and the camera 63 extends from the base 61 until it is located in the inspection area to inspect the joint of the finished tire bead. After the inspection is completed, it exits, and the first actuator 4 can take the inspected finished tire bead from the inspection plate 62 and place the inspected finished tire bead onto the material cart 52 or the non-conforming conveying device 7 according to the inspection results.

[0057] Specifically, the detection disc 62 can be pivotally connected to the base 61 via a servo rotary cylinder. The pivot axis of the detection disc 62 is aligned with the height direction, meaning the tire bead joint detection device 6 is a horizontal device. The camera 63 is not limited to a line laser camera. The camera 63 can be movably connected to the base 61 via a telescopic cylinder and a cable chain. In the detection position, the camera 63 can be located above the detection disc 62, and in the vertical projection plane, the projection of the camera 63 can be located on the outer periphery of the projection of the detection disc 62 in the idle position.

[0058] like Figure 1As shown, in some embodiments, the triangular rubber forming system 1 includes a triangular rubber composite extruder 11, a first detection unit 12, a triangular rubber cooling unit 13, and a second detection unit 14 connected in sequence, with the second detection unit 14 connected to the bead forming system 3.

[0059] The first detection unit 12 includes at least one of the following arranged in sequence: a receiving forced shrinkage device, a continuous weighing device, a first width measuring device, a pressure exhaust device, and a first marking device (which can be added or removed according to process requirements). The second detection unit 14 includes at least one of the following arranged in sequence: a second width measuring device, a final inspection weighing device, and a second marking device. The final inspection weighing device can scan and weigh the triangular rubber. Both the first marking device and the second marking device are used to mark unqualified triangular rubber segments.

[0060] It is understandable that the triangular rubber composite extruder 11 can plasticize the rubber sheets (hard rubber sheet, soft rubber sheet and cushioning rubber sheet) used to produce triangular rubber and then composite them to obtain the desired finished triangular rubber product. The first detection unit 12 performs a first detection on the triangular rubber before cooling, and the second detection unit 14 performs a second detection on the triangular rubber after cooling it in the triangular rubber cooling unit 13, so as to ensure the production quality of the triangular rubber.

[0061] Specifically, the triangular rubber cooling unit 13 can be a spiral cooling structure, using forced air cooling to ensure sufficient cooling capacity without causing changes in the rubber compound. Furthermore, this structure significantly reduces the floor space required for auxiliary lines. The final inspection weighing device primarily detects the shape and weight of the triangular rubber. For example, a cross-sectional scanner can be used to scan the shape of the triangular rubber for higher accuracy. Simultaneously, the weight of the triangular rubber can be measured using a meter scale.

[0062] like Figure 1 and Figure 5 As shown, in some embodiments, a defective product rejection unit 15 is also connected between the second detection unit 14 and the bead forming system 3. The defective product rejection unit 15 is suitable for rejecting defective triangular rubber segments. The defective product rejection unit 15 includes a second conveyor line 151, a cutting device, and a picking mechanism 152. The second detection unit 14 and the bead forming system 3 are connected through the second conveyor line 151, which is used to convey triangular rubber. The cutting device and the picking mechanism 152 are both connected to the second conveyor line 151. The cutting device can cut the triangular rubber to obtain defective triangular rubber segments, and the picking mechanism 152 can grab and transfer the defective triangular rubber segments.

[0063] Furthermore, the defective product rejection unit 15 also includes a defective product cart 153, which is connected to the picking mechanism 152 and is suitable for loading defective triangular rubber segments.

[0064] Understandably, the second conveyor line 151 enables the transfer of triangular rubber between the second detection unit 14 and the tire bead forming system 3, while the cutting device can cut off the defective triangular rubber so that the picking mechanism 152 can pick it up and place it on the defective product cart 153. This allows the processing of defective triangular rubber segments to be carried out automatically in the production line, saving the labor cost of identifying defective triangular rubber, further improving the automation level of the entire line, and ensuring production efficiency.

[0065] Specifically, the second conveyor line 151 is not limited to a conveyor roller conveyor. A cutting device can be installed on the second conveyor line 151, and the cutting device is not limited to including an electric heating knife. The picking mechanism 152 is not limited to a robotic arm. The input end of the second conveyor line 151 is connected to the second detection unit 14, and the output end of the second conveyor line 151 can also be connected to the tire bead forming system 3 through an automatic joint overlapping device to achieve the overlapping of qualified triangular rubber joints, so that the qualified triangular rubber entering the tire bead forming system 3 is continuous rubber material.

[0066] like Figure 1 As shown, in some embodiments, the triangular glue molding system 1 further includes a first storage device 16, and the triangular glue cooling unit 13 is connected to the second detection unit 14 through the first storage device 16. The first storage device 16 is used to temporarily store the triangular glue.

[0067] like Figure 1 As shown, in some embodiments, the triangular rubber forming system 1 further includes a second storage device 17, and the second conveyor line 151 is connected to the tire bead forming system 3 through the second storage device 17. The second storage device 17 is used to temporarily store qualified triangular rubber.

[0068] It is understandable that, since the production speed of the first detection unit 12, the triangular rubber cooling unit 13 and the second detection unit 14 is basically constant and the production is a continuous process, while the production of the bead forming system 3 is achieved by multi-stage speed control, the process of completing one bead bonding is an intermittent process. Therefore, the triangular rubber can be buffered and transitioned through the first storage device 16 and the second storage device 17 to ensure the continuity of production.

[0069] like Figure 1 As shown, in some embodiments, the production line further includes a wire bead transition device 8. The wire bead forming system 2 is connected to the wire bead transition device 8 via a second actuator 21. The second actuator 21 can transfer the finished bead to the wire bead transition device 8. The wire bead transition device 8 is connected to the tire bead forming system 3 via a first actuator 4.

[0070] like Figure 1As shown, in some embodiments, the production line also includes a rim buffer carriage 9, and the wire ring forming system 2 and the wire ring transition device 8 are both connected to the rim buffer carriage 9 via a second actuator 21. The rim buffer carriage 9 is adapted to temporarily store the finished rims of at least one of the wire ring forming system 2 and external input.

[0071] Understandably, the cooperation of the second actuator 21, the wire bead transition device 8, and the first actuator 4 enables the automatic transfer of finished bead rings between the wire bead forming system 2 and the bead forming system 3. The arrangement of the wire bead buffer trolley 9 allows for the storage of finished bead rings when the wire bead forming system 2 is overproducing, and for the use of the finished bead rings stored on the wire bead buffer trolley 9 when production is insufficient. The finished bead rings stored on the wire bead buffer trolley 9 can come from the wire bead forming system 2 or be input from the outside (such as manual input), thus maintaining a semi-automatic mode of finished bead feeding. This improves the flexibility of the production line's working mode, makes maintenance convenient, and can cope with complex industrial environments.

[0072] like Figure 1 As shown, in some embodiments, the wire coil forming system 2 includes a wire supply device 22, a wire coating device 23, a wire winding device 24, and a wire coil wrapping device 25. The wire supply device 22, the wire coating device 23, and the wire winding device 24 are connected in sequence. The wire supply device 22 is used to supply wire. The wire coating device 23 can cover the wire with an adhesive layer to form a coated wire. The wire winding device 24 can wind the coated wire into a wire coil. The wire coil wrapping device 25 is connected to the wire winding device 24 through a third actuator 26 and can wrap the wire coil with cloth to form a finished coil. The wire coil wrapping device 25 is connected to the second actuator 21.

[0073] Understandably, integrating the wire supply device 22, the wire coating device 23, the wire winding device 24, and the rim wrapping device 25 with the tire bead forming system 3 can achieve automated feeding of finished tire bead, thus ensuring the automation level of the entire line.

[0074] It should be noted that the first actuator 4 and the second actuator 21 can both be robots, and the third actuator 26 is not limited to a gantry robot. The specific structure and working principle of the wire feeding device 22, the wire coating device 23, the wire winding device 24, and the steel ring wrapping device 25 can adopt existing technologies in this field, and will not be described in detail here.

[0075] like Figure 1As shown, in some embodiments, the triangular rubber forming system 1, the bead forming system 3, and the wire bead forming system 2 are arranged sequentially along the first direction. There are two bead forming systems 3 and two wire bead wrapping devices 25, which are arranged along the second direction. The second direction is at an angle to the first direction. The wire winding device 24 is located between the two wire bead wrapping devices 25. There are two first actuators 4, which correspond one-to-one with the bead forming system 3. There are two second actuators 21, which correspond one-to-one with the wire bead wrapping devices 25.

[0076] Furthermore, each of the first actuator 4 and the second actuator 21 is pivotally mounted between the bead forming system 3 and the wheel cover device 25, with the first actuator 4 being closer to the bead forming system 3 than the second actuator 21.

[0077] Furthermore, there are two second detection units 14 arranged at intervals along the second direction, and two unqualified rejection units that correspond one-to-one with the second detection units 14.

[0078] Understandably, the production line adopts the above structure, which makes the overall spatial layout more compact. This layout optimizes the flow between steel wire, finished tire bead, and finished tire bead, improving production efficiency and saving labor costs, and greatly enhancing the automation level of the entire line.

[0079] Specifically, the first direction can be the left-right direction in the figure. The second direction can be the front-back direction in the figure. Taking the figure as an example, the triangular rubber composite extruder 11, the first detection unit 12, the triangular rubber cooling unit 13, the first storage device 16, and the second detection unit 14 can be arranged sequentially from right to left. There are two second detection units 14, which are arranged alternately in the front-back direction. The left side of each second detection unit 14 is connected to a defective product rejection unit 15. The left side of the defective product rejection unit 15 is equipped with a second storage device 17. The left side of the second storage device 17 is equipped with a bead forming system 3. There are two bead forming systems 3, which are arranged alternately in the front-back direction. The left side of the bead forming system 3 is equipped with a wire ring forming system 2. The wire ring forming system 2 includes a wire supply device 22, a wire coating device 23, and a wire winding device. The winding device 24 is arranged from left to right. A steel ring wrapping device 25 is arranged on the front and rear sides of the steel wire winding device 24. A steel wire ring transition device 8 is arranged between the steel ring wrapping device 25 and the tire bead forming system 3. A second actuator 21 is arranged between the steel ring wrapping device 25 and the steel wire ring transition device 8. A first actuator 4 is arranged between the steel wire ring transition device 8 and the tire bead forming system 3. There can be two steel ring buffer trolleys 9, which are respectively arranged on the rear (or front) sides of the left and right sides of the second actuator 21. The tire bead stacking conveying system 5, the tire bead joint detection device 6, and the unqualified conveying device 7 are all arranged around the first actuator 4 and are all located on the rear (or front) side of the tire bead forming system 3. The overall spatial layout is compact.

[0080] like Figure 1 As shown, in some embodiments, the bead forming system 3 includes a feeding device 31, a bonding drum 32, and a pressing device 33 connected in sequence. The feeding device 31 is connected to the triangular adhesive forming system 1 and can supply qualified triangular adhesive to the bonding drum 32. The bonding drum 32 is connected to the first actuator 4 and can be connected to the finished bead so that qualified triangular adhesive is bonded to the finished bead. The pressing device 33 is used to press the bonded triangular adhesive joint on the finished bead to form the finished bead.

[0081] Specifically, the feeding device 31 may be a servo feeding device, including a main pneumatic frame, a traversing assembly, a conveyor roller, a cutting component, and a delivery device. The bonding drum 32 may include a fixed base 61, a rotating housing, and a drum body. The pressing device 33 may include pressing rollers and pressing cylinders.

[0082] The bead forming system 3 can realize online cutting, conveying, automatic winding and closing, automatic pressing of joints, and flipping forming of triangular rubber. Among them, the servo feeding device has accurate positioning and correction functions. All conveying and cutting are servo controlled to ensure the accuracy and reliability of the feeding process and achieve complete formulation. In addition, the servo feeding device can also have an automatic head and tail overlapping mechanism to further realize the fully automated production line. At the same time, the servo feeding device also achieves rubber tensioning and positioning in the entire process of cutting, head and tail conveying through the cooperation of various mechanisms, ensuring the continuity of triangular rubber production and the quality of the finished product.

[0083] The bonding drum 32 can be an adjustable mechanical drum, which has a pre-support function, allowing for better bonding of the finished bead and triangular adhesive, reducing the possibility of detachment and improving the tightness of the bead bonding. Therefore, the bonding disc structure can be eliminated, saving on finished product manufacturing and optimizing the bonding process, reducing production cycle time. Through a dual-station switching working mode, it can automatically perform winding and flipping forming processes, which can adapt to the production of multi-specification products within a certain range. This not only improves production efficiency but also greatly reduces production costs. In addition, the speed control of the bonding drum 32 and the servo feeding device can be achieved by servo speed matching to improve the accuracy and stability of the product joint.

[0084] The bonding drum 32 works in conjunction with the first actuator 4 to perform the upright forming of the tire bead on the forming side of the drum body through coordinate transformation. This working method is stable, reliable, easy to control, and produces uniform products with a high degree of coverage of the steel ring. The pressing device 33 can adopt a multi-plate pressure roller structure, which can automatically match various triangular rubber specifications and automatically complete the pressing of the joint.

[0085] It should be noted that the production line can also have a complete control program system, including linkage control of various parts of the production line, formula control of products of different specifications, manual operation function, maintenance and debugging function, safety protection function, etc., which will not be elaborated here.

[0086] The working process of this automated triangular rubber bead production line will now be explained in detail, based on its specific structure:

[0087] S1. The upper triangular rubber, lower triangular rubber and filler sheet are compounded in the triangular rubber compound extruder 11 and continuously extruded to form triangular rubber. After forming, the triangular rubber passes through the first detection unit 12, the triangular rubber cooling unit 13, the first storage device 16 and the second detection unit 14 in sequence, and then enters the second conveyor line 151 of the defective product rejection unit 15 to reject the defective triangular rubber segments.

[0088] At the same time, the wire supply device 22 supplies the wire to the wire coating device 23 for coating, and then the wire winding device 24 winds it into a wire loop. After that, with the assistance of the third actuator 26, the wire loop enters the wire loop wrapping device 25 for wrapping, forming a finished loop.

[0089] S2. The qualified triangular rubber enters the tire bead forming system 3, and the finished bead moves to the wire bead transition device 8 or the wire bead buffer trolley 9 with the assistance of the second actuator 21. The bonding drum 32 rotates to the forming side, and the first actuator 4 transfers the finished bead on the wire bead transition device 8 to the bonding drum 32.

[0090] S3. The triangular rubber is continuously conveyed by the conveyor roller on the servo feeding device. The delivery device lifts the head of the triangular rubber and delivers it to the designated position on the bonding drum 32. The bonding drum 32 rotates to wrap the triangular rubber body. The cutting component cuts the triangular rubber laterally. The delivery device delivers the tail of the triangular rubber to the bonding drum 32 to join with the head of the triangular rubber. The pre-pressing mechanism initially presses the joint of the triangular rubber on the bonding drum 32. The cylindrical rubber strip after being wrapped and sealed is rotated to the flipped position. The bonding drum 32 rotates the joint to the pressing start angle. The pressing device 33 then presses down the pressing plate roller. The bonding drum 32 rotates a certain angle to ensure that the pressing plate roller presses the entire joint, thus completing the forming of the triangular rubber bead.

[0091] S4. The first actuator 4 transports the upright finished tire bead to the tire bead joint detection device 6 for detection. If the detection is passed, the tire bead is transported to the stacking position 512. If the detection is failed, the tire bead is transported to the unqualified conveying device 7.
