Because the endless conveyor belt 11 and the feeding conveyor 40 are both servo-driven, synchronous conveying of the two conveyor belts can be achieved through servo control.

4. When the material head of the right side curtain 80 is continuously conveyed to the position of the second position detecting part 62, the position of the material head edge part of the right side curtain 80 is detected by the second position detecting part 62, and a position signal is transmitted to the control part 63.

Before the head of the right side curtain 80 is continuously conveyed to the position of the second position detecting part 62, the position of the tail part of the left side curtain 80 is detected and determined in advance, and a position signal is transmitted to the control part 63.

6. As shown in fig. 6, after receiving the position signal of the material head of the right curtain 80, the control part 63 compares the position signal with the position signal of the left curtain 80, calculates and analyzes the correction amount required for correction, and drives the endless belt 11 to move through the correction mechanism 20, that is, the material head of the right curtain 80 moves, so that the material head of the right curtain 80 is aligned with the position of the left curtain 80.

7. The actions are synchronously completed in the normal feeding process of the right side curtain cloth 80 and before positioning, so that no extra time is occupied, the joint efficiency is not influenced by the deviation rectifying action, and the joint efficiency is ensured.

8. The material head part of the right curtain cloth 80 reaches the material tail part of the left curtain cloth 80 to perform the jointing action.

9. And after the joint action is finished, the cord fabric is subjected to the discharging positioning action and the feeding action.

10. The above actions are repeated to form a continuous joint cycle.

11. Fig. 7 is a schematic view of the misalignment between the material head portion of the right side curtain cloth 80 and the material tail portion of the left side curtain cloth 80, where the misalignment is X. The misalignment may be both vertical and vertical, so the value of X may be positive or negative.

12. Fig. 8 is a schematic diagram after deviation correction, where b is c, when the width b of the right curtain 80 is set to be equal to the width c of the left curtain 80, and the deviation correction amount is X.

13. Fig. 9 is a post-correction diagram in which the width b of the right side curtain 80 and the width c of the left side curtain 80 are set to be unequal, that is, b ≠ c, and width detection is not employed. Due to the fact that width detection is not carried out, when the widths of the curtain cloth are unequal, single-side alignment can be achieved only by single-side rectification. This can be used without much effect from the change in the width of the curtain.

14. Fig. 10 is a schematic post-correction diagram in which the width b of the right side curtain 80 and the width c of the left side curtain 80 are set to be unequal, that is, b ≠ c, and the width detection is performed by a width detection section (CCD). The values of the widths b and c are detected by the CCD and transmitted to the control section 63. At this time, the deviation correction amount can be calculated according to different positive and negative values of X and the difference value between b and c, and the misalignment difference value between the right curtain 80 and the left curtain 80 is Y after deviation correction, namely the center lines are aligned.

15. When the angles alpha of the two curtains 80 are different, the position of the endless conveyor belt 11 relative to the joint line can be moved back and forth along the feeding direction by the adjusting mechanism 30 in advance, so that the position of the endless conveyor belt 11 is as close as possible to the position of the joint line to adapt to different angles.

16. When the width b of the right curtain 80 changes, the position of the endless conveyor belt 11 can be moved left and right in the width direction by changing the initial position of the deviation correcting mechanism 20, so as to adapt to different curtain widths.

The utility model discloses a formula deviation correcting device is inhaled to magnetism, realizes connecting the synchronous automatic deviation rectification of curtain cloth at the initiative feed in-process in the synchronous of carrying through servo drive's endless conveyor belt 11 and feed transport area, does not occupy and connects cycle time, has improved joint efficiency, and the highest joint efficiency reaches 24/minute. And real-time closed-loop control of joint misalignment is realized through a closed-loop detection and correction system, and the precision of joint misalignment is greatly improved. The misalignment precision of the joint is less than or equal to 0.5mm, and the requirement of the joint precision of the current high-end tire equipment is met.

Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
