The tipping paper is used for tipping cigarettes and filter tips, particularly, the tipping of the cigarettes and the filter tips in the cigarette production process is to place a double-length filter tip between two cigarettes without filter tips, bond the glued tipping paper with the double-length filter tip and the two cigarettes without filter tips, and then cut the middle of the double-length filter tip to obtain two finished cigarettes.

In the actual production process, the tipping paper can be inevitably deviated from the inside and the outside due to various reasons such as inconsistent central points of supports of tipping paper trays and inconsistent central points of replaced tipping paper, so that the tipping paper is not positioned between a double-length filter tip and two cigarettes without filter tips when being wrapped, but in order to ensure that the lengths of the two cut cigarettes are consistent, a cutting point is still positioned between the double-length filter tips, so that the lengths of the tipping paper of the inner cigarette and the outer cigarette are inconsistent, and the tipping paper is judged to be an unqualified product when the length difference exceeds 0.5mm according to the conventional product quality control mechanism; meanwhile, the cutting point is not on the glue-free line, so that defective products such as hair cutting smoke and the like are easily formed after the cutting blade collects glue; particularly, when the tipping paper is too large in deviation, the filter tip and cigarette package are bonded too little to generate filter tip dropping cigarettes, which belongs to a first-level important quality defect.

The current solution is that two optical fiber sensors are used for detecting two side edges of tipping paper to enter a cutting drum, when one of the optical fiber sensors detects the existence of the tipping paper, a servo motor is controlled to move, a transparent paper adjusting mechanism moves the transparent paper towards the other side, and the servo motor stops rotating until the optical fiber sensors on the two sides do not detect the transparent paper.

This current scheme has the loaded down with trivial details problem of optical fiber sensor position adjustment, needs in equipment operation process, makes china cypress paper keep the correct position of predetermineeing and regard this as the reference to carry out optical fiber sensor position adjustment, and simultaneously, two optical fiber sensors need keep certain interval with china cypress paper edge, and this is difficult to realize accurate control in actual operation.
