Problems solved by technology
However, due to the singleness of the functions of these spinning frames, when it is necessary to doff in the middle, it can only be doffed manually, and when the yarn needs to be wound to a certain length, automatic doffing cannot be completed, and manual doffing not only The efficiency is low, and the work is cumbersome, labor-intensive, and requires a large number of personnel
However, in order to pursue higher spinning efficiency, the production range of the spinning frame is limited, which cannot meet the needs of customers for fixed-length yarns.
[0004]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

The invention provides an automatic doffing device applicable to the technical field of textile machinery. The automatic doffing device comprises an automatic doffing mechanism, a yarn winding length adjusting mechanism and a PLC, wherein the PLC is electrically connected with the automatic doffing mechanism and the yarn winding length adjusting mechanism. The invention further provides a doffing method of a spinning machine including the automatic doffing device. According to the automatic doffing device and the doffing method, the automatic doffing in a full pipe state can be realized, the fixed length doffing can be realized through regulation, namely the automatic doffing is realized when the yarn is wound to a certain length, the yarn winding length can be regulated according to requirements after doffing, and the midway automatic doffing is realized, so that the spinning efficiency is improved, the manpower demand is reduced, furthermore, different demands of customers for the yarns are met, and the flexible application of the spinning machine is realized.
Description
technical field [0001] The invention relates to the technical field of textile machinery, in particular to an automatic doffing device and a doffing method of a spinning frame including the device. Background technique [0002] With the upgrading of textile machinery, spinning frame long car with automatic doffing has become the mainstream in today's market. [0003] The automatic doffing here mainly refers to the automatic doffing of full bobbins, that is, automatic doffing is performed only after the yarn reaches the set fullness value on the bobbin. However, due to the singleness of the functions of these spinning frames, when it is necessary to doff in the middle, it can only be doffed manually, and when the yarn needs to be wound to a certain length, automatic doffing cannot be completed, and manual doffing not only The efficiency is low, and the work is cumbersome, labor-intensive, and requires a large number of personnel. In order to pursue higher spinning efficienc...
