Description
Technical Field
The utility model relates to a cigarette machine automated control technical field specifically relates to a tipping paper length detection device.
Background
The tipping length of tipping paper is an important index of cigarette appearance quality. The tipping length tolerance of tipping paper is generally ± 0.5 mm. On a high-speed unit with the speed more than 7000 pieces per minute, an operator is difficult to accurately measure tipping paper running at high speed in real time in the running state of the equipment, and even if the error direction and the accurate adjustment quantity are measured, the wrapping lengths of the inner and outer tipping paper of the produced filter tip cigarette exceed the tolerance range, so that the appearance of the cigarette is influenced and the quality of the cigarette is reduced.
Through analysis of a large amount of data in the operation process of the cigarette assembler, the following main reasons for causing tipping paper drift are found:
1. tension of tipping paper is not uniform
The tipping paper has certain elasticity, and the straightness can be changed under different tensions, and particularly after passing through a plurality of paper feeding rollers, a certain amount of displacement can be generated under the influence of the large and small tensions. The tension of the tipping paper of the conventional cigarette plug assembler is balanced by adopting a spring brake, a feedback system is not arranged, the tension cannot be well matched due to various reasons after the tipping paper is used for a period of time, and the position drift of the tipping paper is generated during variable-speed operation, particularly the drift phenomenon is most obvious during variable-speed and splicing of the cigarette plug assembler.
2. Tipping paper disc deflection
The mounting position changes due to the fact that the tipping paper disc is replaced newly or old, or certain deflection can be generated in the unreeling process due to the fact that the tipping paper disc is not rolled uniformly, is not mounted properly and the like, so that the tipping paper is fed in a snake shape, and the paper feeding position of the new and old tipping paper discs changes when spliced.
3. Error in mechanical transmission
The tipping paper passes through a long distance from uncoiling to tipping, and has a plurality of stations for gluing, heating and cutting. In the process, the accumulated error of the mechanical transmission is large, and the accumulated error is also an important reason for the length change of the tipping paper. The width of the guide rails will generally be greater than the width of the tipping paper and will also result in uncontrolled waving of the tipping paper.
At present, the detection of the length of the tipping paper mainly comprises the following steps:
1. the tension of the tipping paper is ensured by additionally arranging a tension detection and control mechanism, such as a tension counterweight method, a tension sensor method and the like. The method can improve the tension stability of tipping paper to a certain extent, but cannot detect whether the length after tipping is qualified or not.
2. The method only partially solves the problem of non-centering of the guide rail by additionally arranging the photoelectric deviation rectifying system, counteracts the quick change deviation rectifying caused by the serpentine shape of the bobbin paper, and completely fails to detect the mechanical transmission error from the guide rail to the connection part.
The third type is an image detection method, and the length of the tipping paper of the cigarette is calculated by oblique shooting at the export drum wheel. However, the method can only sample and detect about 30% of cigarettes, the oblique shooting is sensitive to the installation position, so that the adjustment is difficult, and in addition, the shooting at the leading drum cannot judge the error direction.
