[0002] Currently, there are two main types of belt drum feeding devices for tire building machines. One type primarily uses manual cutting to feed materials, occupying a relatively small footprint but with a relatively low degree of automation, resulting in low efficiency and additional labor costs. The other type primarily uses automatic cutting to feed materials, with a relatively high degree of automation.

[0046] The automatic feeding device for the belt drum station provided in this embodiment, when working according to the feeding sequence, its working principle and steps include: S1, using feeding device 2 to feed belt layer No. 1 after horizontal switching of belt layer No. 1 and No. 3: After the No. 1 and No. 3 belt layers are switched horizontally, the feeding part 2 is in the initial position, that is, the No. 1 belt layer feeding position. The No. 1 belt layer is guided away by the No. 1 belt layer guide device 15, and then passed through the material pocket between the No. 1 belt layer guide device 15 and the No. 1 belt layer conveying device 17, and is conveyed to the feeding entrance of the No. 1 belt layer conveying device 17. The feeding entrance is provided with a mechanical side guard device that adjusts the inner spacing according to the width of the No. 1 belt layer. The No. 1 belt layer is centered by the mechanical side guard device. And continue to convey forward, when conveyed to the gap between No. 1 belt layer conveying device 17 and the lower layer No. 1 and No. 3 belt layer swing frames 9, the deviation of No. 1 belt layer is detected by the first correction detection device, and the No. 1 belt layer conveying device 17 is driven to move laterally by the electric cylinder according to the detected deviation, so as to ensure that when No. 1 belt layer is conveyed to the lower layer No. 1 and No. 3 belt layer swing frames 9, No. 1 belt layer conveying device 17 is completely aligned with the lower layer No. 1 and No. 3 belt layer swing frames 9.

[0047] The first fixed-length detection device is provided on the lower layer No. 1 and No. 3 belt layer swing frames 9. When the No. 1 belt layer material head passes through the first fixed-length detection device, the conveying servo motor on the lower layer No. 1 and No. 3 belt layer swing frames 9 starts counting. When it is determined that the distance between the No. 1 belt layer material head and the center of the No. 1 belt layer cutting device 19 is equal to the required No. 1 belt layer length, the conveying is stopped. Then the No. 1 belt layer cutting device 19 cuts the No. 1 belt layer. After cutting, the No. 1 belt layer is conveyed to the front end of the lower layer No. 1 and No. 3 belt layer swing frames 9.

[0048] During the forward conveying process, the first fixed-length detection device on the lower layer No. 1 and No. 3 belt layer swing frame 9 can calculate the actual length of No. 1 belt layer according to the position of the tail of the No. 1 belt layer detected when the tail of the No. 1 belt layer passes through. At this time, the lower layer No. 1 and No. 3 belt layer swing frame 9 swings downward and extends, and the lower layer No. 1 and No. 3 belt layer swing frame 9 conveys No. 1 belt layer forward, and at the same time the belt drum starts to rotate; wherein, by comparing the actual length of No. 1 belt layer with the theoretical length, the conveying speed of No. 1 belt layer and the rotation speed of the belt drum are controlled, if the actual length is less than the theoretical length, the conveying speed is controlled to be slower than the rotation speed; if the actual length is greater than the theoretical length, the conveying speed is controlled to be faster than the rotation speed, and finally it is ensured that the No. 1 belt layer is just connected end to end and fits on the belt drum, thereby ensuring its fitting effect on the belt drum.

[0049] S2, feeding the No. 2 belt layer by using the No. 2 belt layer rear feeding device 3: 2 belt layer is guided away by the No. 2 belt layer guide-out device 22, and then passed through the material bag between the No. 2 belt layer guide-out device 22 and the No. 2 belt layer conveying device 23, and then conveyed to the loading entrance of the No. 2 belt layer conveying device 23. The loading entrance is provided with a mechanical side guard device which adjusts the inner spacing according to the width of the No. 2 belt layer. The No. 2 belt layer is centered by the mechanical side guard device and continues to be conveyed forward. When it is conveyed to the gap between the No. 2 belt layer conveying device 23 and the upper No. 2 belt layer swing frame 8, the deflection of the No. 2 belt layer is detected by the second deviation correction detection device, and the No. 2 belt layer conveying device 23 is driven to move laterally by the electric cylinder according to the detected deflection, so as to ensure that when the No. 2 belt layer is conveyed to the upper No. 2 belt layer swing frame 8, the No. 2 belt layer conveying device 23 is completely aligned with the upper No. 2 belt layer swing frame 8.

[0050] A second fixed-length detection device is provided on the upper No. 2 belt layer swing frame 8. When the No. 2 belt layer material head passes through the second fixed-length detection device, the conveying servo motor on the upper No. 2 belt layer swing frame 8 starts counting. When it is determined that the distance between the No. 2 belt layer material head and the center of the No. 2 belt layer cutting device 24 is equal to the required No. 2 belt layer length, the conveying is stopped. Then the No. 2 belt layer cutting device 24 cuts the No. 2 belt layer, and after cutting, the No. 2 belt layer is conveyed to the front end of the upper No. 2 belt layer swing frame 8.

[0051] During the forward conveying process, the second fixed-length detection device on the upper No. 2 belt layer swing frame 8 can calculate the actual length of the No. 2 belt layer according to the position of the tail of the No. 2 belt layer detected when the tail of the No. 2 belt layer passes through. At this time, the upper No. 2 belt layer swing frame 8 swings downward and extends, and the lower No. 1 and No. 3 belt layer swing frames 9 are in the lower limit position retracted state, and the upper No. 2 belt layer swing frame 8 conveys the No. 2 belt layer forward, and at the same time the belt drum starts to rotate; wherein, by comparing the actual length of the No. 2 belt layer with the theoretical length, the conveying speed of the No. 2 belt layer and the rotation speed of the belt drum are controlled. If the actual length is less than the theoretical length, the conveying speed is controlled to be slower than the rotation speed; if the actual length is greater than the theoretical length, the conveying speed is controlled to be faster than the rotation speed, and finally it is ensured that the No. 2 belt layer is just connected end to end and fits on the belt drum, thereby ensuring its fitting effect on the belt drum.

[0052] S3, using feeding device 2 to feed belt layer No. 3 after horizontal switching of belt layer No. 1 and No. 3: After the lateral switching of the No. 1 and No. 3 belt layers, the feeding part 2 is in the initial position, that is, the feeding position of the No. 1 belt layer. The servo motor on the mobile frame 14 drives the mobile frame 14 and the related devices installed on the mobile frame 14 to slide along the transverse guide mechanism 13 through the chain transmission, and switches to the feeding position after the No. 3 belt layer, and aligns with the swing frame 9 of the No. 1 and No. 3 belt layers on the lower layer. 3 belt layer is guided away by the No. 3 belt layer guide-out device 16, and then passed through the material bag between the No. 3 belt layer guide-out device 16 and the No. 3 belt layer conveying device 18, and is conveyed to the feeding inlet of the No. 3 belt layer conveying device 18. The feeding inlet is provided with a mechanical side guard device which adjusts the inner spacing according to the width of the No. 3 belt layer. The No. 3 belt layer is centered by the mechanical side guard device and continues to be conveyed forward. When it is conveyed to the gap between the No. 3 belt layer conveying device 18 and the lower layer No. 1 and No. 3 belt layer swing frame 9, the deflection of the No. 3 belt layer is detected by the first deviation correction detection device, and the No. 3 belt layer conveying device 18 is driven to move laterally by the electric cylinder according to the detected deflection, so as to ensure that when the No. 3 belt layer is conveyed to the lower layer No. 1 and No. 3 belt layer swing frame 9, the No. 3 belt layer conveying device 18 is completely aligned with the lower layer No. 1 and No. 3 belt layer swing frame 9.

[0053] The first fixed-length detection device is provided on the lower layer No. 1 and No. 3 belt layer swing frame 9. When the No. 3 belt layer material head passes through the first fixed-length detection device, the conveying servo motor on the lower layer No. 1 and No. 3 belt layer swing frame 9 starts counting, and stops conveying when it is determined that the distance between the No. 3 belt layer material head and the center of the No. 3 belt layer cutting device 20 is equal to the required No. 3 belt layer length. Then the No. 3 belt layer cutting device 20 cuts the No. 3 belt layer, and after cutting, the No. 3 belt layer is conveyed to the front end of the lower layer No. 1 and No. 3 belt layer swing frame 9.

[0054] During the forward conveying process, the first fixed-length detection device on the lower layer No. 1 and No. 3 belt layer swing frame 9 can calculate the length of the No. 3 belt layer according to the position of the tail of the No. 3 belt layer detected when the tail of the No. 3 belt layer passes through. At this time, the lower layer No. 1 and No. 3 belt layer swing frame 9 swings downward and extends, and the lower layer No. 1 and No. 3 belt layer swing frame 9 conveys the No. 3 belt layer forward, and at the same time the belt drum starts to rotate; wherein, by comparing the actual length of the No. 3 belt layer with the theoretical length, the conveying speed of the No. 3 belt layer and the rotation speed of the belt drum are controlled. If the actual length is less than the theoretical length, the conveying speed is controlled to be slower than the rotation speed; if the actual length is greater than the theoretical length, the conveying speed is controlled to be faster than the rotation speed, and finally it is ensured that the No. 3 belt layer is just connected end to end and fits on the belt drum, thereby ensuring its fitting effect on the belt drum.

[0055] S4, using the front feeding lamination and zero-degree belt layer feeding equipment 1 to feed the zero-degree belt layer: The zero-degree belt layer is guided away by the zero-degree belt layer guiding device 12, and then tightened by the zero-degree belt layer tensioning device 11, and then transported to the loading entrance of the zero-degree belt layer swing frame 10. The loading entrance is provided with a mechanical side guard device that adjusts the internal spacing according to the width of the zero-degree belt layer. The zero-degree belt layer is positioned by the mechanical side guard device, and finally the zero-degree belt layer material head is fixed by adsorption by the magnet installed at the front end of the zero-degree belt layer swing frame 10. When the zero-degree belt layer is being bonded, the zero-degree belt layer swing frame 10 extends, and the zero-degree belt layer head is manually pulled and attached to the belt drum according to the positioning position of the light mark line. Then the belt drum starts to rotate, and the zero-degree belt layer on the zero-degree belt layer swing frame 10 is passively transported forward. At the same time, the zero-degree belt layer tensioning device 11 continuously tightens the zero-degree belt layer to ensure the bonding tension. After bonding is completed, the zero-degree belt layer tail is manually cut with electric scissors, and the zero-degree belt layer tail is attached to the belt drum, and the zero-degree belt layer head is re-adsorbed on the magnet installed at the front end of the zero-degree belt layer swing frame 10. When a roll of zero-degree belt layer is used up, the sensor on the zero-degree belt layer deflection device 12 detects the tail of the material, and controls the pneumatic clamp on the zero-degree belt layer tensioning device 11 to clamp the zero-degree belt layer, thereby preventing the zero-degree belt layer from being completely transported out of the zero-degree belt layer tensioning device 11 and avoiding re-threading when changing materials.

[0056] S5, using the tread rear feeding device 4 to feed the tread: The tread is guided away by the tread guide device 25, and then passes through the material pocket between the tread guide device 25 and the tread feed conveying device 26, and is conveyed to the feeding entrance of the tread feed conveying device 26. The feeding entrance is provided with an automatic deviation correction device, through which the tread is centered and continues to be conveyed forward. The tread feed conveying device 26 is provided with a fixed length detection device. When the tread material head passes the fixed length detection device, the conveying servo motor on the tread feed conveying device 26 starts counting to determine whether the tread material head is close to the tread cutting device. When the distance between the centers of the treads 27 reaches the desired tread length, the conveying is stopped, and the tread cutting device 27 cuts the tread. After cutting, the tread is completely conveyed to the tread transverse conveying device 29. Then, the motor on the tread transverse conveying base 28 drives the tread transverse conveying device 29 to move transversely through the synchronous belt, so that the transverse conveying device 29 can be aligned with the tread swing frame 7. Then, the tread transverse conveying device 29 and the tread swing frame 7 are conveyed forward synchronously, and the tread is gradually conveyed from the tread transverse conveying device 29 to the tread swing frame 7. A 3D camera is provided behind the tread swing frame 7 to scan and record the tread profile during the forward conveyance of the tread, detect the deviation of each tread segment relative to the tread swing frame 7, and measure the actual length of the tread.

[0057] Next, the tread swing frame 7 is swung downward. At this time, the lower layer No. 1 and No. 3 belt layer swing frames 9 and the upper layer No. 2 belt layer swing frame 8 are both in the retracted state at the lower limit position. The tread swing frame 7 is transported forward, and at the same time, the belt drum begins to rotate. The tread conveying speed and the belt drum rotation speed are controlled by comparing the actual length of the tread with the theoretical length. If the actual length is less than the theoretical length, the conveying speed is controlled to be slower than the rotation speed; if the actual length is greater than the theoretical length, the conveying speed is controlled to be faster than the rotation speed, ultimately ensuring that the tread is exactly connected end to end and attached to the belt drum, thereby ensuring its bonding effect on the belt drum. In addition, during the bonding process, according to the tread deviation detected by the 3D camera, the tread swing frame 7 is driven by a motor to move laterally to ensure that the tread and the belt drum are completely aligned after the tread is bonded.

[0058] It should be noted that the above steps are only used as an example, and in the actual production process, the above steps can be selected according to the actual tire process.

[0059] The technical effects of the automatic feeding device for the belt drum station provided in this embodiment are as follows: The automatic feeding device for the belt drum station provided in this embodiment is used to realize the feeding of three layers of angled belt layers, one layer of zero-degree belt layer, and one layer of tread. The specific number of angled belt layer stations and zero-degree belt layer stations used can be determined according to the corresponding tire blank specification structure. For example, a separate station is set for the zero-degree belt layer near the first row of the front guide rail, and the No. 1 and No. 3 belt layers are arranged in parallel near the second row of the front guide rail. The stations can be switched horizontally according to the feeding demand and share the lower belt layer swing frame; the No. 2 belt layer is located near the third row of the front guide rail. The tread unwinding is arranged on the side of the No. 2 belt layer unwinding. After loading, it is moved horizontally to the feeding frame by the upper mobile conveyor device to realize feeding. In addition, both the belt layer and the tread are automatically cut and fed by rolling, which ultimately makes the overall layout of the automatic feeding device for the belt drum station compact, occupies a small space, and takes into account the advantages of a high degree of automation.
