(2) And scanning the code information of each passing spun yarn bobbin on the conveyor belt by a code scanner III, and transmitting the code information to the database to be compared with the found code information on the spun yarn bobbin produced by the lagging spindle, so as to determine whether the passing spun yarn bobbin is a defective spun yarn bobbin produced by the lagging spindle.
(3) When the scanned spun yarn bobbin is determined to be a defective yarn bobbin through database comparison, the database starts a limit sensor; when the limit sensor senses that the bobbin passes through, the limit sensor transmits a signal to the second motor to enable the conveying belt to stop at a set position.
(4) And after the conveying belt stops, the database transmits a defective yarn bobbin removing instruction to the removing structure, controls the removing structure to act, and removes defective yarn bobbins from the conveying belt. The specific removing process comprises the following steps:
(41) after the eliminating structure receives the instruction signal of the database, the first motor rotates to drive the gear to rotate, and then the rack is driven to move.
(42) The rack pushes the pushing block and the ejector rod to horizontally move towards the direction of the conveying belt, when the pushing block moves to the position of a defective yarn bobbin, the head of the pushing block is inserted into the bottom end of the defective yarn bobbin, and the fixed end of the conveying belt, which is used for fixing the defective yarn bobbin, is just arranged in the middle strip-shaped opening of the pushing block, so that the pushing block cannot be hindered from moving.
(43) The inclined plane contacted with the bottom end of the defective yarn bobbin is gradually raised along with the continuous forward pushing of the pushing block, so that the defective yarn bobbin is driven to be lifted upwards; in the process that the defective yarn bobbin is upwards supported, the clamping groove limits the defective yarn bobbin, and when the defective yarn bobbin rises to be separated from the fixed end on the conveying belt, the defective yarn bobbin is toppled over under the pushing action of the ejector rod and falls into a yarn bobbin frame on one side of the conveying belt.
(44) And then the first motor rotates reversely, the pushing block and the ejection rod are driven to return to the original position through the gear and the rack, and a next removing instruction is waited.
(5) And after the defective yarn bobbins are removed from the conveying belt, the conveying belt continues to rotate, and the spun yarn bobbins are conveyed into a yarn storage of the automatic bobbin winder.
Furthermore, the system also comprises a sorting device 5 for empty tubes and defective bobbins behind the automatic bobbin winder, so that the empty tubes and the defective bobbins can be automatically sorted.
