Background
Bobbin paper splicing refers to splicing the in-use bobbin paper and the standby bobbin paper together so as to meet the requirement of continuous production. In the existing cigarette making and splicing machine set, bobbin paper splicing adopts online dynamic lapping of double-sided adhesive tapes, and the double-sided adhesive tapes are moved to positions between double layers of bobbin paper to be spliced by utilizing a swing cylinder to rotate a swing arm. Because the bobbin paper is dynamically spliced, the running speed of the standby bobbin paper needs to be matched with the linear speed of the in-use bobbin paper.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Examples
Fig. 1 is a schematic flow chart of a bobbin paper splicing method according to an embodiment of the present invention. As shown in fig. 1, the present embodiment provides a method for splicing bobbin paper, including:
and 101, acquiring the thickness of the remaining bobbin paper.
In some embodiments, the thickness of the remaining bobbin paper may be obtained in a variety of ways, for example, by obtaining an image of the remaining bobbin paper, determining edge information of the remaining bobbin paper in the image according to an edge detection algorithm, determining the thickness of the remaining bobbin paper according to the edge information; the thickness of the residual bobbin paper can be detected in real time by arranging a thickness detection device.
And 102, if the thickness reaches a preset value, sending a splicing instruction to a splicing device so that the splicing device splices the residual bobbin paper and the replacement bobbin paper.
In the embodiment, the thickness of the remaining bobbin paper is obtained first, and when the thickness reaches the preset value, a splicing instruction is sent to the splicing device, so that the splicing device splices the remaining bobbin paper and the replacement bobbin paper, and thus, the thickness of the remaining bobbin paper is directly obtained, and whether the bobbin paper needs to be replaced is judged according to the thickness.
Fig. 2 is a schematic flow chart of a bobbin paper splicing method according to another embodiment of the present invention. As shown in fig. 2, the present embodiment provides a method for splicing bobbin paper, including:
In some embodiments, the image of the remaining bobbin paper can be captured in real time by arranging a camera in front of the remaining bobbin paper.
In some embodiments, the bobbin paper is usually wound on the bobbin paper winding device, and the obtained image of the remaining bobbin paper is an annular picture, so that the gray transition position in the image is determined to be the edge of the bobbin paper by using an edge detection algorithm. In addition, after the image is acquired, the image may be gray-processed first to better determine the gray transition position.
Optionally, the edge detection algorithm may be, but is not limited to, any one of a differential operator, a Canny operator, and a LOG operator.
In this embodiment, a LOG (laplacian) operator is used, which is a second order differential operator independent of edge direction, and is a scalar rather than a vector. The method has the advantages that the position where the gray level transition occurs in the image can be accurately judged, so that the bobbin paper edge is identified, and materials are provided for thickness detection. The reason for selecting it is that it has high boundary positioning accuracy, strong anti-interference ability and good continuity.
And step 203, determining the gray transition position as the edge information of the remaining bobbin paper.
In some embodiments, the image of the remaining bobbin is in the shape of a ring, and thus the gray level transition position in the image is the edge position of the bobbin.

Based on the above embodiment, the image of the remaining bobbin paper is a part of the image, so that when the thickness of the remaining bobbin paper is calculated, the gray level jump-in position in the image is two curves, that is, two pieces of edge information, at this time, the thickness of the remaining bobbin paper can be obtained only by calculating the difference between the radii of the two curves, and based on this, only the difference value of each point in different pieces of edge information needs to be calculated, and the minimum value is taken as the thickness of the remaining bobbin paper in the image.
And step 205, calculating the thickness of the residual bobbin paper according to the ratio of the minimum value to the preset thickness.
In some embodiments, the preset thickness ratio may be calculated according to the actual size of the remaining bobbin paper and the size of the remaining bobbin paper in the image, and the thickness of the remaining bobbin paper may be obtained by multiplying the minimum value obtained in the above embodiments by the preset thickness ratio.
And step 206, if the thickness reaches a preset value, sending a splicing instruction to a splicing device so that the splicing device splices the residual bobbin paper and the replacement bobbin paper.
In some embodiments, the preset value may be set according to actual conditions, for example, an image is taken when the remaining bobbin paper is nearly used up, and the thickness of the bobbin paper is calculated as the preset value.
It can be understood that, instead of calculating the thickness of the remaining bobbin paper by the preset thickness ratio, the preset value may be set as the minimum value of the remaining bobbin paper in the image, and the minimum value in the above embodiment may be compared with the preset minimum value in the set image.
