Description

Printing production line

Technical Field

The utility model relates to the technical field of printing, in particular to a printing production line.

Background

Printing lines generally include printing equipment (e.g., commercial rotary presses), cutting and folding equipment, and stacking equipment. The printing equipment is used for printing images and texts on the paper, the cutting and folding equipment is used for processing the paper printed with the images and texts into signatures, and the stacking equipment is used for stacking a plurality of signatures into a stack; the paper transfer between the printing equipment and the cutting and folding equipment can be manual carrying or equipment transfer; transfer of signatures between cutting and folding devices is typically accomplished by a conveying device (e.g., a conveyor). In the actual production process, the number of good labels of each type of label printing machine is generally required to be controlled according to the number of orders and the requirement of work orders.

At present, a metering sensor is arranged in the cutting and folding equipment so as to meter the quantity of the book labels output by the cutting and folding equipment; arranging a full-time staff at the conveying equipment between the cutting and folding equipment and the stacking equipment, checking the books conveyed on the conveying equipment by the full-time staff, placing the found bad books into a collecting basket (the collecting basket is placed on a wagon balance), weighing the total weight of the collecting basket and the bad books through the wagon balance, and further calculating the number of the bad books in the collecting basket (for example, setting the number of the bad books as Y and the weight of single books as M) ₁ The weight of the collecting basket is M ₂ The indication number of the wagon balance is M ₃ Then there is Y= (M) ₃ -M ₂ )/M ₁ ) The method comprises the steps of carrying out a first treatment on the surface of the The number of produced good-quality books can be obtained by subtracting the number of bad books from the number of books output by the cutting and folding device. The quantitative (gram weight of paper per square meter) of paper generally has a certain deviation range (the deviation of delivery quantitative of paper specified by a general paper factory is within +/-4 percent), and meanwhile, the paper is subjected to the influence of environmental temperature and humidityThe weight change caused by water absorption or release is also relatively large, so that after the number of bad signatures received in the collection basket is large, the calculated number of bad signatures and the number of bad signatures put into the collection basket have large deviation, and the finally calculated number of good signatures and the number of good signatures actually produced have large deviation.
