Example 8

The basic structure of the splicing trolley with the single-spindle suction nozzle of the embodiment is the same as that of the embodiment 7, and the differences and improvements are as follows: the method comprises the following steps:

step one, positioning a splicing trolley: after the splicing trolley receives the splicing signal, a motor 57 in a traversing mechanism 5 of the splicing trolley drives a conveyor belt 55 to move, and the conveyor belt 55 drives the splicing mechanism 3 on the base 1 to move to the front of a corresponding spindle;

step two, introducing negative pressure: the yarn suction nozzle 72 is arranged at the upper zero position sensor 78, negative pressure is provided through the upper air duct 6, and the yarn suction nozzle 72 is communicated with the negative pressure air pipe 61 in the upper air duct 6;

step three, sucking the upper broken tail yarn: starting a motor on the yarn suction nozzle 72 to enable the yarn suction nozzle 72 to be aligned with a roller yarn outlet above the splicer 31, and enabling the yarn suction nozzle 72 to start sucking the broken tail yarn;

step four, preparing broken tail yarns: the yarn suction nozzle 72 moves downwards to the position of a lower zero position sensor 79, a swing air cylinder 77 is started to drive the driving wheel 741 to rotate in the forward direction, and then a synchronous wheel 742 is driven to rotate in the same direction through a synchronous belt 744 wound on the driving wheel, so that a suction nozzle elbow 71 mounted on the driving wheel is controlled to rotate, and further the yarn suction nozzle 72 connected with the lower part of the suction nozzle elbow 71 is driven to move downwards to the position of the lower zero position sensor 79, the yarn suction nozzle 72 carries an upper broken tail yarn to move downwards and sends the upper broken tail yarn to the inner side of a yarn holding mechanism 32 in front of the splicer 31, the longitudinal movement mechanism 4 pushes out the splicer seat 2, and the splicer mechanism 3 moves forwards along with the splicer seat 2, so that the yarns enter a yarn groove iii 313 and a yarn groove iii;

step five, absorbing broken yarn of the bobbin: the large suction nozzle 9 below the splicer 31 is driven by the cylinder to descend to the cheese suction nozzle 8 and align with the cheese suction nozzle 8, and then the bobbin broken yarn is sucked;

step six, preparing broken yarn of the bobbin: then, the large suction nozzle 9 is driven to move upwards by the air cylinder, the sucked bobbin broken yarn is lifted to the front of a yarn groove I313, then an air cylinder I331 is started, and the yarn clamping mechanism 316 is driven to clamp the yarn tail of the bobbin broken yarn;

step seven, yarn splicing: starting a control switch of the splicer 31 to form high-speed airflow; then, the cylinder I is opened to I332, the upper scissors 315 and the lower scissors 317 are driven to cut off redundant yarns, and the yarn holding mechanism 32 sends the yarns into the splicer 31 to complete the splicing operation;

step eight, splicing is finished: the longitudinal moving mechanism 4 retracts the splicer seat 2, and the splicer mechanism 3 moves back to the original position along with the splicer seat 2; the yarn suction nozzle 72 returns to the upper zero position sensor 78, the swing air cylinder 77 is started to drive the driving wheel 741 to rotate reversely, and then the synchronous wheel 742 is driven to rotate in the same direction through the synchronous belt 744 wound on the driving wheel, so that the nozzle elbow 71 mounted on the driving wheel is controlled to rotate, and the yarn suction nozzle 72 connected with the lower portion of the nozzle elbow 71 is driven to move upwards to the upper zero position sensor 78.

In the above step, since the nozzle elbow 71 can rotate and the yarn can move, the traversing mechanism 5 or the longitudinally moving mechanism 4 of the splicing trolley needs to be controlled to adjust to the left and right or front and back directions respectively according to the position of the yarn, so as to adjust the positions of the yarn groove i 313 and the yarn groove ii 314, and the yarn can accurately enter the yarn groove i 313 and the yarn groove iii 314.

In addition, in the fourth step, when the yarn suction nozzle 72 fails to reach the lower zero sensor 79, the single spindle gives an alarm, so that the maintainers can specifically find the cause of the accident, the maintenance can be smoothly completed, unnecessary downtime is reduced, and the production efficiency is improved.
