Method for splicing bobbin paper of cigarette making machine

Abstract

The invention discloses a method for splicing bobbin paper of a cigarette making machine. The method comprises the following steps that: a controller operably connected with each air cylinder, a bobbin paper cutter and a bobbin paper drive roller is provided; the controller starts a second bobbin paper drive roller to transmit second bobbin paper till the transmitting speed of the second bobbin paper is the same as the transmitting speed of the first bobbin paper when a mark detector detects a first mark, wherein the mark detector is arranged on the downstream of a first air cylinder and a second air cylinder along a work bobbin paper adjacent path, and the first mark is arranged on the first bobbin paper and keeps a first distance with an inner ring of the first bobbin paper; the second air cylinder moves to jack the second bobbin paper wound around a tension roller of the second air cylinder outside to be propped against the first bobbin paper when the mark detector detects a second color block, and the second bobbin paper is adhered and lapped with the first bobbin paper wound around the tension roller of the first air cylinder through an adhesive, wherein the second mark is arranged on the first bobbin paper and keeps a second distance with the inner ring of the first bobbin paper, and the second distance is smaller than the first distance; and the controller drives a bobbin paper cutter arranged on the downstream side of the tension roller of the second air cylinder and a bobbin paper cutter arranged on the upstream side of the tension roller of the first air cylinder to respectively cut off the first bobbin paper and the second bobbin paper, thus the second bobbin paper as a spare bobbin paper is converted into working bobbin paper.

Description

technical field [0001] The invention relates to a method for splicing paper coils used in cigarette machines. Background technique [0002] At present, when splicing the coils of the PASSIM cigarette machine (cigarette equipment produced by the British Molins Company) in the prior art, it is judged when to splice the coils by detecting the diameter of the coils. This is achieved by comparing the number of pulses generated when the coil rotates with the speed and diameter settings of the cigarette maker during the time period. Such as figure 1 As shown, the first and second paper trays 3 and 3' are wound on the first and second paper tray inner rings 2 and 2' respectively, and are tightly fastened on the first and second paper tray holders 1 and 4, when When the cigarette making machine is running, the first paper tray 3 as the current working tray is drawn away, driving the first paper tray 1 to rotate. Protruding teeth are evenly distributed on the inner surface of the p...

AI Technical Summary

Problems solved by technology

[0003] This type of paper splicing method has low precision, the signal is easily disturbed, and the diameters of the working paper during splicing are different.

And when the working diameter is too small when splicing, it will cause the working disc paper to be spliced ​​to be used up before splicing, which will cause splicing failure

In order to ensure smooth splicing, the method of increasing the splicing diameter of the coils is usually adopted. The remaining coils after splicing are about 21 meters, accounting for about 0.42% of the entire 5000 meters of coils, and the waste of coils is large.
