after entering the shading shell 1 from the feeding hole 2, a bed product firstly passes through the guide mechanism, in the process, high-speed airflow generated by the fan 3 is sprayed outwards through the flat nozzle 25 to remove impurities such as dust, floating hair and broken lines on the surface of the bed product, meanwhile, the temperature increasing plate 24 heats the airflow, the drying effect of the bed product can be improved, the air pump 6 is simultaneously started to pump the air in the shading shell 1 outwards, so that raised impurities such as dust enter the dust filtering box 4 along the airflow, and the cleanness of the interior of the shading shell 1 is ensured;

when the bedding enters the area where the detection mechanism is located, the industrial camera 35 transmits images to an external computer, the external computer analyzes the position, the type and the number of the flaws through an algorithm, and simultaneously sends corresponding computer instructions to the marking device 38, so that the magnetic labels are attached to the flaws (the magnetic labels are only attached to the front side of the bedding);

when the bed product moves to the lower positioning table 9 through the discharge port 23, the detection port 10 can detect whether the magnetic labels pass through or not and the number (number) of the passed magnetic labels through the Hall effect;

assuming that the first defect is located on the front side of the bedding, the serial number of the magnetic label is 1, the second defect is located on the back side of the bedding, the serial number of the magnetic label is 2, the third defect is located on the back side of the bedding, and the serial number of the magnetic label is 3, when the bedding passes through the marking device 38, the external computer can automatically map the serial number to the position of the defect, so as to distinguish whether the defect is located on the front side or the back side of the bedding;

after the magnetic label with the serial number 1 passes through the detection port 10, the external computer sends an instruction to the driving seat 15 to enable the magnetic label with the serial number 1 to move towards the direction of the lower positioning strip 11, meanwhile, the negative pressure machine 16 is started, the negative pressure plate 17 captures the bedding by using negative pressure, after the lower positioning strip 11 senses the magnetic label with the serial number 1, the external computer controls the driving seat 15 to stop, and at the moment, the first flaw is located at one end, far away from the shading shell 1, of the lower positioning table 9, so that a worker can repair the first flaw conveniently;

in the process of repairing by workers, the electric telescopic rod 7 is contracted, and the distance adjusting roller 28 is driven to move upwards through the fixing block 22, so that the movement of the bedding in the horizontal direction is converted into the movement in the vertical direction, and the bedding is prevented from being stacked;

after the repairing of workers is finished, the driving seat 15 is reset, the electric telescopic rod 7 is extended, so that the bed product gradually recovers to move, in the process, the speed of the bed product passing through the feeding hole 2 and the discharging hole 23 is unchanged, and the equipment is not stopped;

after the magnetic label with the serial number 2 passes through the detection port 10, the driving seat 15 moves to the upper positioning table 13 along the track 14, the negative pressure plate 17 drives the bed product to be tiled on the upper positioning table 13, the back of the bed product faces upwards, when the magnetic label with the serial number 2 is sensed by the upper positioning strip 21, the driving seat 15 stops moving, a worker can repair a second defect, and the distance adjusting roller 28 also moves upwards during repair;

it should be noted that, one end of the bedding is to be fixed at the wind-up roll 19, the wind-up roll 19 is driven by the servo motor 20 to rotate to wind up the repaired bedding, the rotation speed of the output shaft of the servo motor 20 is adjusted according to the movement condition of the bedding, and the surface of the bedding is kept flat, that is, in the above process, when the magnetic label passes through the detection port 10 until the repair is completed, the rotation speed of the output shaft of the servo motor 20 is zero;

after the magnetic label with the serial number 3 passes through the detection port 10, similarly, the driving seat 15 can move to the upper positioning table 13, so that a worker can conveniently repair the defect on the back of the bed, the worker does not need to manually turn over the bed, and secondary defect detection is not needed.
