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

[0036] like Figure 1 As shown, an automated production line for apex rubber tire beads according to an embodiment of the present invention comprises an apex rubber molding system 1, a wire ring molding system 2 and a tire bead molding system 3, the apex rubber molding system 1 is connected with the tire bead molding system 3, the apex rubber molding system 1 is suitable for molding apex rubber and can convey the apex rubber to the tire bead molding system 3, the wire ring molding system 2 is connected with the tire bead molding system 3 through a first actuator 4, the wire ring molding system 2 is suitable for molding finished tire beads, the first actuator 4 can move the finished tire beads to the tire bead molding system 3, so that the tire bead molding system 3 can fit the apex rubber to the finished tire beads to form a finished tire bead.

[0037] It can be understood that according to the automated production line for the triangular rubber tires of the embodiment of the present invention, the production line for the entire triangular rubber tires is constructed by integrating the triangular rubber molding system 1, the wire ring molding system 2 and the tire ring molding system 3, wherein the triangular rubber molding system 1 can convey the triangular rubber to the tire ring molding system 3, and at the same time the first actuator 4 can transfer the finished tire ring molded by the wire molding system to the tire ring molding system 3, so that the tire ring molding system 3 can produce the finished tire ring by bonding the triangular rubber on the finished tire ring, thereby realizing the automated coordination and connection between the various processes of the entire line. Therefore, compared with the related art, the present invention can realize the automated production of triangular rubber tires, with high production efficiency and low labor cost, and can ensure the consistency of the quality of batch triangular rubber tire production.

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

[0039] It can be understood that the method of moving the finished tire beads by the first actuator 4 to the tire bead stacking and conveying system 5 for stacking and storage not only realizes the automatic unloading and stacking of the finished tire beads, further improves the automation performance of the production line, but also uses the same first actuator 4 to realize the circulation of finished rings and finished tire beads in the whole line, which can also reduce the footprint of 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 logistics cart 52. The first conveyor line 51 has an entry position 511, a stacking position 512 and an exit position 513. The logistics cart 52 is connected to the first conveyor line 51 and is suitable for circulating in sequence between the entry position 511, the stacking position 512 and the exit position 513. The logistics cart 52 can be connected with the first actuator 4 at the stacking position 512 so that the first actuator 4 can stack the finished tire beads and store them on the material cart.

[0041] It can be understood that since the material cart is connected to the first conveyor line 51, the first conveyor line 51 can drive the material cart to automatically flow between the entry position 511, the stacking position 512 and the exit position 513 in sequence, cooperating with the first actuator 4 to ensure the continuity of the entire line production while realizing the automatic transfer of the finished tire ring.

[0042] like Figure 1 and Figure 2As shown, in some embodiments, the tire bead stacking and conveying system 5 also includes a spacer grabbing device 53, which is suitable for taking and placing spacers and can be connected with the logistics trolley 52 at the stacking position 512, so as to place spacers between any two adjacent finished tire beads. The spacers are used to separate and stack the finished tire beads, thereby avoiding the influence of the extrusion force between the two on the quality of the finished tire beads.

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

[0044] It can be understood that the parking entry position 511, the grabbing position 514, the stacking position 512 and the parking exit position 513 are all integrated on the first conveyor line 51, so that the logistics cart 52 can realize the sequential circulation between the various workstations when moving with the first conveyor line 51. At the same time, the spacer grabbing device 53 can grab the spacer from the logistics cart 52 on the grabbing position 514, and place it on the logistics cart 52 on the side for carrying the finished tire ring, which further improves the structural compactness of the spatial layout of the entire line.

[0045] Specifically, the first conveyor line 51 is not limited to a conveyor roller. The logistics trolley 52 can enter the parking position 511 with a full load of spacers, and the spacers on it can be transferred one by one to the logistics trolley 52 at the stacking position 512 by the spacer grabbing device 53 at the grabbing position 514, until the logistics trolley 52 at the grabbing position 514 is empty, and the logistics trolley 52 at the stacking position 512 fully loaded with finished tire rims moves to the parking position 513, and the empty logistics trolley 52 at the grabbing position 514 enters the stacking position 512 to prepare for the continued stacking of finished tire rims.

[0046] Furthermore, the tire bead stacking and conveying system 5 can be electrically connected to the AGV system for communication, so that the tire bead stacking and conveying system 5 has the function of automatic entry and exit, that is, when the logistics cart 52 fully loaded with finished tire bead is located at the exit parking space 513, the tire bead stacking and conveying system 5 will feedback to the AGV system, and the AGV system will take out the logistics cart 52 from the parking space 513. At the same time, when there is no logistics cart 52 in the parking space 511, the tire bead stacking and conveying system 5 will also communicate with the AGV system, so that the AGV system can send the logistics cart 52 fully loaded with spacers into the parking space 511, thereby realizing the automatic transfer of spacers and finished tire bead logistics.

[0047] like Figure 3 As shown, in some embodiments, the spacer grabbing device 53 includes a main frame 531, a mounting seat 532, a lifting drive 533, a swing arm 534 and a spacer claw 535. The mounting seat 532 is movably connected to the main frame 531 along the height direction. The lifting drive 533 is installed on the main frame 531 and is transmission-connected to the mounting seat 532 so as to adjust the height position of the mounting seat 532 on the main frame 531; the swing arm 534 is pivotally connected to the mounting seat 532 through a rotary drive 536, and the direction of the pivot axis of the swing arm 534 is consistent with the height direction, so that the rotary drive 536 can adjust the horizontal position of the swing arm 534 relative to the logistics trolley 52, and the spacer claw 535 is installed on the swing arm 534 and is suitable for being connected to the spacer.

[0048] It can be understood that, by cooperating with the lifting drive 533 and the rotating drive 536, the position of the swing arm 534 on the main frame 531 can be adjusted to facilitate the spacer claw 535 to grab the spacer from the logistics cart 52 at the grabbing position 514, and transfer the spacer to the finished tire ring at the stacking position 512, thereby completing the automatic picking and placing operation of the spacer. At the same time, the spacer grabbing device 53 is an overall vertical structure, which occupies a small 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 a motor and a drag chain. The rotation drive 536 may not be limited to a swing cylinder. The main frame 531 may extend in the height direction, that is, the up and down direction in the figure.

[0050] like Figure 3 As shown, in some embodiments, the septum grabbing device 53 also includes a grabbing probe and a buffer cylinder, both of which are installed on the swing arm 534. The grabbing 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, thereby effectively avoiding the risk of the septum claw 535 causing damage to the septum when the swing arm 534 descends excessively.

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

[0052] Furthermore, the spacer claw 535 is a conical spacer claw 535 and has a guiding cone surface. The guiding cone surface can be movably connected to the inner circumferential surface of the spacer along the extension direction of the guiding cone surface to guide the spacer to be centered on the spacer claw 535. The guiding cone surface structure reduces the contact area with the spacer and reduces the risk of the spacer claw 535 damaging the spacer tooling. Under the guidance of the guiding cone surface, the influence of misaligned 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 an unqualified conveying device 7, both of which are connected to the first actuator 4, and 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 unqualified conveying device 7 is used to transfer unqualified finished bead. The unqualified conveying device 7 is not limited to using a conveyor line.

[0054] It can be understood that the tire bead stacking and conveying system 5, the tire bead joint detection device 6 and the unqualified conveying device 7 form a matching system, which realizes the automatic detection of the tire bead joint while meeting the production efficiency, reduces manual intervention, greatly improves the automation level of the entire line, and ensures the production quality of the finished tire bead.

[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, and the detection disk 62 can rotate the joint of the finished tire bead to the detection area so that the camera 63 can obtain image information of the joint of the finished tire bead. The camera 63 is separated from the detection area at the idle position so that the first actuator 4 can transfer the finished tire bead.

[0056] It can be understood that after the first actuator 4 places the finished tire bead produced by the tire bead forming system 3 on the inspection disk 62, the inspection disk 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 and exit after the inspection is completed. The first actuator 4 can then take the inspected finished tire bead from the inspection disk 62 and place the inspected finished tire bead on the logistics cart 52 or the unqualified conveying device 7 according to the inspection results.

[0057] Specifically, the detection plate 62 can be pivotally connected to the base 61 through a servo rotary cylinder, and the direction of the pivot axis of the detection plate 62 is consistent with the height direction, that is, 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 is movably connected to the base 61 through a telescopic cylinder and a drag chain. The camera 63 can be located above the detection plate 62 at the detection position, and on the projection surface in the vertical height direction, the projection of the camera 63 can be located on the outer peripheral side of the projection of the detection plate 62 at the idle position.

[0058] like Figure 1As shown, in some embodiments, the apex molding system 1 includes an apex composite extruder 11, a first detection unit 12, an apex cooling unit 13 and a second detection unit 14 connected in sequence, and the second detection unit 14 is connected to the tire bead molding system 3.

[0059] The first detection unit 12 includes at least one of a receiving forced shrinkage device, a continuous weighing device, a first width measuring device, a pressure exhaust device and a first marking device arranged in sequence (these devices can be increased or decreased according to process requirements). The second detection unit 14 includes at least one of a second width measuring device, a final inspection scale device and a second marking device arranged in sequence. The final inspection scale device can scan and weigh the apex glue. The first marking device and the second marking device are both used to mark unqualified apex glue segments.

[0060] It can be understood that the films (hard films, soft films and buffer films) for producing apex films can be plasticized and compounded by the apex composite extruder 11 to obtain the desired apex finished product, and the first detection unit 12 can perform a primary detection on the apex before cooling, and after the apex is cooled by the apex cooling unit 13, the second detection unit 14 can perform a secondary detection on the apex to ensure the production quality of the apex.

[0061] Specifically, the apex cooling unit 13 can be a spiral cooling structure, and adopts a forced air cooling method, so as to meet the cooling capacity without causing the quality change of the rubber material. In addition, this structure greatly reduces the footprint of the auxiliary line. The final inspection scale device mainly detects the shape and weight of the apex. For example, a cross-sectional scanner can be used to scan the shape of the apex, which has higher detection accuracy. At the same time, the weight of the apex can be measured by 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 tire bead forming system 3. The defective product rejection unit 15 is suitable for rejecting defective apex 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 tire bead forming system 3 are connected via the second conveyor line 151. The second conveyor line 151 is used to convey the apex rubber. The cutting device and the picking mechanism 152 are both connected to the second conveyor line 151. The cutting device can cut the apex rubber to obtain defective apex rubber segments. The picking mechanism 152 can grab and transfer the defective apex rubber segments.

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

[0064] It can be understood that the second conveyor line 151 can realize the circulation of the apex rubber between the second detection unit 14 and the tire bead forming system 3, and the cutting device can cut off the unqualified apex rubber so that it can be grabbed by the picking mechanism 152 and placed on the unqualified product cart 153, so that the processing of the unqualified apex rubber segments can be automatically carried out in the production line, saving the labor cost of distinguishing unqualified apex rubber, further improving the automation level of the whole line, and ensuring production efficiency.

[0065] Specifically, the second conveyor line 151 may not be limited to a conveyor roller. The cutting device may be installed on the second conveyor line 151, and the cutting device may not be limited to an electric hot knife. The picking mechanism 152 may not be limited to a manipulator. 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 may also be connected to the tire bead forming system 3 through an automatic joint overlap device to achieve the overlap of the qualified apex joint, so that the qualified apex entering the tire bead forming system 3 is a continuous rubber material.

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

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

[0068] It can be understood that since the production speeds of the first detection unit 12, the apex rubber cooling unit 13 and the second detection unit 14 are basically kept uniform and the production is in a continuous process, and the production of the tire bead forming system 3 is achieved by multi-stage speed control, the process of completing a tire bead fitting is an intermittent process. Therefore, the apex rubber buffer transition can be performed 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 also includes a wire ring transition device 8, the wire ring forming system 2 is connected to the wire ring transition device 8 through a second actuator 21, the second actuator 21 can transfer the finished ring to the wire ring transition device 8, and the wire ring transition device 8 is connected to the tire bead forming system 3 through the first actuator 4.

[0070] like Figure 1As shown, in some embodiments, the production line also includes a steel ring cache trolley 9, and the steel ring forming system 2 and the steel ring transition device 8 are connected to the steel ring cache trolley 9 through a second actuator 21, and the steel ring cache trolley 9 is suitable for temporarily storing finished rings of at least one of the steel ring forming system 2 and external input.

[0071] It can be understood that the cooperation between the second actuator 21, the wire ring transition device 8 and the first actuator 4 can realize the automatic flow of finished rings between the wire ring forming system 2 and the tire bead forming system 3, and the arrangement of the wire ring cache trolley 9 can store the finished rings when the wire ring forming system 2 has overproduction, and can use the finished rings stored on the wire ring cache trolley 9 for transitional production when production is insufficient. The finished rings stored on the wire ring cache trolley 9 can come from the wire ring forming system 2 or external input (such as manual input) to retain the semi-automatic mode of finished ring feeding, thereby improving the flexibility of the working mode of the production line, facilitating maintenance, and being able to cope with complex industrial environments.

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

[0073] It can be understood that integrating the steel wire supply device 22, the steel wire rubber coating device 23, the steel wire winding device 24 and the steel ring cloth wrapping device 25 with the tire bead forming system 3 can realize the automatic feeding of the finished tire rings to ensure 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 manipulator. The specific structures and working principles of the steel wire supply device 22, the steel wire glue coating device 23, the steel wire winding device 24 and the steel ring wrapping device 25 can adopt the existing technology in the field, and will not be repeated here.

[0075] like Figure 1As shown, in some embodiments, the apex rubber molding system 1, the tire bead molding system 3 and the wire ring molding system 2 are arranged in sequence along the first direction, there are two tire bead molding systems 3 and two wire ring wrapping devices 25 and they 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 ring wrapping devices 25, there are two first actuators 4 and they correspond one-to-one to the tire bead molding systems 3, and there are two second actuators 21 and they correspond one-to-one to the wire ring wrapping devices 25.

[0076] Further, each of the first actuator 4 and the second actuator 21 may be pivotally mounted between the bead forming system 3 and the flipper device 25 , and the first actuator 4 is closer to the bead forming system 3 than the second actuator 21 .

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

[0078] It is understandable that the production line adopts the above structure, and the spatial layout of the entire line is more compact. This layout optimizes the flow mode between steel wire-finished ring-finished tire ring, improves production efficiency and saves labor costs, and the automation level of the entire line is greatly improved.

[0079] Specifically, the first direction may be the left-right direction in the figure. The second direction may be the front-back direction in the figure. Taking the figure as an example, the apex rubber composite extruder 11, the first detection unit 12, the apex rubber cooling unit 13, the first storage device 16 and the second detection unit 14 may be arranged in sequence from right to left. There are two second detection units 14 and they are arranged at intervals in the front-back direction. The left side of each second detection unit 14 is connected to a defective product rejection unit 15. The second storage device 17 is arranged on the left side of the defective product rejection unit 15. The tire bead forming system 3 is arranged on the left side of the second storage device 17. There are two tire bead forming systems 3 and they are arranged at intervals in the front-back direction. The wire bead forming system 2 is arranged on the left side of the tire bead forming system 3, wherein the wire supply device 22, the wire rubber coating device 23 and the wire winding device 2 in the wire bead forming system 2 The winding devices 24 are arranged from left to right in sequence, a steel ring cloth wrapping device 25 is arranged on the front and rear sides of the steel wire winding device 24 respectively, a steel ring transition device 8 is arranged between the steel ring cloth wrapping device 25 and the tire bead forming system 3, and a second actuator 21 is arranged between the steel ring cloth wrapping device 25 and the steel ring transition device 8, and a first actuator 4 is arranged between the steel ring transition device 8 and the tire bead forming system 3. There can be two steel ring buffer carts 9 and they are arranged on the rear side (or front side) 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 surrounded by the first actuator 4 and are all located on the rear side (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 tire 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 apex rubber forming system 1 and can supply qualified apex rubber 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 the qualified apex rubber can be bonded to the finished bead, and the pressing device 33 is used to press the apex rubber joint bonded on the finished bead to form the finished tire bead.

[0081] Specifically, the feeding device 31 may be a servo feeding device, including a main pneumatic frame, a traverse assembly, a conveying roller, a cutting component and a delivery device. The laminating drum 32 may include a fixed base 61, a rotating box and a drum body. The laminating device 33 may include a laminating sheet roller and a laminating cylinder.

[0082] The bead forming system 3 can realize the functions of online cutting, conveying, automatic winding closure, automatic pressing joints, and flip forming of the apex rubber. Among them, the servo feeding device has an accurate positioning and correction function. All conveying and cutting are controlled by servo to ensure the accuracy and reliability of the feeding process and realize full formulation. In addition, the servo feeding device can also have a head-tail automatic overlap mechanism to further realize the full automatic production of the production line. At the same time, the servo feeding device also cooperates with each other through various mechanisms to realize the tension and positioning of the rubber in the entire process of cutting, head-tail conveying, etc., ensuring the continuity of apex rubber production and the quality of the products.

[0083] The bonding drum 32 can be structurally an adjustable mechanical drum with a pre-support function, which can better fit the finished bead and the apex rubber, reduce the possibility of falling off, and improve the tightness of the bead fit. Therefore, the bonding disc structure can be eliminated, saving manufacturing finished products, optimizing the bonding process, reducing the production cycle, and through the double-station switching working mode, automatic winding and flip forming processes are performed respectively, which can adapt to the production of multiple specifications of products within a certain range, not only improving production efficiency but also greatly reducing production costs. In addition, the speed control method 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 laminating drum 32 cooperates with the first actuator 4 to perform the bead turning and forming by coordinate conversion on the forming side of the drum body. This working mode is stable and reliable, easy to control, and the products produced are uniform and the degree of steel ring coverage is high. The pressing device 33 can adopt a multi-piece pressing roller structure, which can automatically match a variety of apex specifications and automatically complete the joint pressing.

[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, recipe control of products of different specifications, manual operation function, maintenance and debugging function, safety protection function, etc., which will not be elaborated here.

[0086] Now, combined with the specific structure of the automatic production line of the triangle rubber bead, its working process is explained as follows:

[0087] S1, the upper apex, the lower apex and the filling film are compounded in the apex compound extruder 11 and then continuously extruded to form an apex. The formed apex passes through the first inspection unit 12, the apex cooling unit 13, the first storage device 16 and the second inspection unit 14 in sequence, and then enters the second conveying line 151 of the unqualified product rejection unit 15 to reject the unqualified apex segments;

[0088] At the same time, the steel wire supply device 22 supplies the steel wire to the steel wire coating device 23 for coating, and then the steel wire winding device 24 winds the steel wire into a steel wire ring, and then enters the steel ring cloth wrapping device 25 for cloth wrapping with the assistance of the third actuator 26 to form a finished ring;

[0089] S2, the qualified apex rubber enters the bead forming system 3, and the finished bead is moved 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 apex is continuously conveyed by the conveying roller on the servo feeding device, the conveying device lifts the head of the apex and delivers it to the designated position on the bonding drum 32, the bonding drum 32 rotates to wrap the apex colloid, the cutting component cuts the apex horizontally, the conveying device delivers the tail of the apex to the bonding drum 32 to engage with the head of the apex, the pre-pressing mechanism preliminarily presses the apex joint on the bonding drum 32, the cylindrical rubber strip after winding and closing is rotated to the flipping position, the bonding drum 32 rotates the joint to the starting angle of pressing, the pressing device 33 then presses the pressing sheet roll down, the bonding drum 32 rotates a certain angle, ensures that the pressing sheet rolls the entire joint, and completes the forming of the apex tire bead;

[0091] S4, the first actuator 4 transports the finished tire bead that has been turned over to the tire bead joint detection device 6 for detection. If the detection passes, the tire bead is transported to the stacking position 512; if the detection fails, the tire bead is transported to the unqualified conveying device 7.
