Of course, when placing the coil for the first time, it is necessary to manually wind the cloth head region of the cloth coil located at the tail end of the cloth coil conveyor 40 onto the powered winder 8, when the first coil is detected to be completed, the cloth tail region of the coil is detected by a sensor (not shown in the figure), and when the cloth tail region is detected, the powered winder 8 stops winding, and the subsequent coil can be operated according to the following steps.

s1, detecting a cloth head area of the cloth roll at the tail end of the cloth roll conveyor 40 by a sensor (not shown in the figure), starting the telescopic mechanism 62 of the material grabbing mechanism 6 to move the pneumatic clamping jaw 61 to the cloth head area, starting the pneumatic clamping jaw 61 to clamp and fix the cloth head area, and then driving the pneumatic clamping jaw 61 to retract and move above a cloth tail area of the cloth to be detected by the telescopic mechanism 62, wherein the cloth tail area and the cloth head area are both located above the lower pressing block 1.

s2, at this time, the cylinder shaft of the cylinder 401 of the lifting device 40 extends, the upper pressing block 2 moves towards the lower pressing block 1, and after the bottom surface of the upper pressing block 2 contacts with the cloth head area, the upper pressing block 2 moves continuously, so as to cooperate with the lower pressing block 1 to press the cloth head area and the cloth tail area between the upper pressing block 2 and the lower pressing block into a wave-shaped wrinkle shape; at this time, the needle pushing mechanism 5 moves down along with the upper pressing block 1, and the pushing block 51 is embedded into the notch 34 of the second guide rail 32 outside the needle box or is located outside the notch.

S3, the telescopic shaft of the cylinder 54 of the needle pushing mechanism 5 retracts, so as to drive the pushing block 51 to move towards the direction of the lower pressing block, and during the movement, the pushing block pushes the needle 42 in the corresponding needle groove 41 to the first channel and the second channel, so as to sew the cloth head area and the cloth tail area together.

And S4, the powered winding machine 8 is started again to carry out winding, the image acquisition device acquires image information of the cloth surface in real time along with the movement of the cloth so that the control device can analyze whether the corresponding area is defective, in addition, in the detection process, the encoder 70 positioned at the rear part of the image acquisition device 10 records the detection length, and data basis is provided for determining the position of the corresponding defective point.

And S5, when the control device determines that a cloth area corresponding to a certain image has a defect point, the control device controls the defect point marking device 30 to spray ink and the like to mark the defect point so as to avoid product defects by cutting or sewing up the corresponding area when the subsequent cloth is used.

S6, simultaneously, the metal sensor 20 constantly detects whether metal exists on the cloth surface passing through the detection area, if yes, the position of the corresponding metal is recorded through data of an encoder, when the cloth moves to the cloth inspecting machine, the cloth inspecting machine is stopped, metal is removed manually, and then the equipment is started manually to continue inspection; also, since the needles 42 used to sew the different rolls of cloth are also typically metal, when a metal sensor senses the needle 42, it will also stop at the appropriate location on the cloth inspection machine for manual removal of the needle 42, allowing the two sewn rolls of cloth to be separated, thereby allowing the cloth to be split into multiple rolls.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
