Feed machine material detecting system based on grating sensor

Abstract

The invention provides a feed machine material detecting system based on a grating sensor. An existing primary processing line tobacco feeder material detecting mode and the model selection and installation of the grating sensor are optimized. The system is characterized in that a photoelectric switch at the feed end of a primary processing workshop super-back ZS1 feeder is improved, and it is avoided that material breakage is caused when tobacco leaves block the photoelectric switch. The grating sensor is installed on an adjustable installation support. The installation position of the adjustable installation support makes the grating sensor detect materials in the feeder through an observation window in a material storage bin of the feeder. After the improvement, detection errors of single-point detection of an ordinary photoelectric switch can be reduced; meanwhile, by designing the adjustable installation support, the detection position of the grating sensor can be conveniently adjusted, and the accuracy and the stability of detection of the materials in the feeder are improved. After the improvement, the situation that material breakage at a super-back process point is caused when tobacco leaves block the photoelectric switch in the material storage bin of the feeder is effectively reduced, and the breakdown frequency is reduced.

Description

technical field [0001] The invention relates to a material detection system of a feeder based on a grating sensor, which belongs to the field of material detection of tobacco thread. Background technique [0002] At present, the super-return feeding machine in the first workshop of Yuxi Cigarette Factory frequently causes material breakage in the batch. According to the system records, there were 11 times of material breakage in the batch from December 1, 2015 to January 20, 2016. 8 times for the 5-ton line and 3 times for the 10-ton line, seriously affecting the continuity of production. According to the fault records, all 11 times of material breakage were caused by the same reason, which was that the sheet was attached to the glass to block the high material level photoelectric switch, resulting in material breakage. [0003] Three preventive measures have been taken since December: strengthening monitoring and maintenance, improving the discharge port to adjust the airf...

Problems solved by technology

After the implementation of the three measures, although the occurrence of material breakage has been reduced to a certain extent, the effect is not very good, and the problem cannot be solved fundamentally

To solve the problem fundamentally, there are two ways. The first method is to use anti-adhesive materials on the glass surface to avoid the adhesion of tobacco leaves. At present, no suitable implementation method can be found; the second method is to use grating photoelectric sensors instead of the currently used ones. single point detection switch
